I sure did forget this. Its been buried in my PM box for ages.
For a long time I gave this some thought and haven't found the right way to express myself regarding this piece. The other day another Mod added THIS and I remembered this and frankly if that was allowed then there should be no problem with this piece at all since it is better, by far. The piece on that page however is not the one that was there before so now I really have no way to express my concerns with this piece at all, versus that one. Not that I judge pieces against each other but I swear I have a point to make.
If there is one single thing that makes something pixelart vs. oekaki, its precise pixel placement and care in form and lines and angles. I don't see a lot of that here and was the reason I had sent it back.
If you wish to re-submit this piece I'll bring it to the other Mods attention and mention this piece vs. that crap I linked too. If that one is in then this one should be too and I would owe you an apology and wish that Brazil wins the World Cup from now on every 4 years, plus the Gold in the Brazil Olympics (but only that Olympics) 
no worries jal, do it when you can and feel like it. I'm not really fond of this piece either way, I'm just taking the opportunity to discuss a bit
Oh man this is always the most difficult conversation to have. I'll have to do so in a it since I swamped right now. I'll reply proper in a day or so.
(Please do not see this as a hissy-fit or an attempt to overthrow whatever or whatever drama is going on, I'm asking with the bewildered curiosity of a learning child)
The answer is probably "both", but is it more about pixel placement or colour choices?
For intsance, would this quick edit be approved, while the original piece wasn't on account of colours? Of course this is a very crude recolour, these colour would be applied differently if used from start, but if "this is Pixelaki and not quite pixelart because of coloring techniques, or rather the lack of them", would this recolour version be ok? If so, couldn't it be merely a matter of preference?
Then again, about pixel placement...Yes, it could be more precise (it always can, even when I did try for pieces with clear outlines and what not), but does it have to? One thing is the pixel aesthetic, but from what I gathered round through the years, pixel art is more of a medium than a proper movement, innit? Then surely must be space for different styles, including scruffy and messy ones? There aren't NPA elements, I just didn't want the piece to have 1 pixel lines. I've done cleaner stuff before, and grew uninterested. But it's still pixel art...or not? I placed, consciously, each and every single pixel on the image. No program decided adding pixels or changing pixel colours, and it's not randomly scribbled. It's a lot more loose, but not as free-handed or random as oekaki, I guess...or maybe it is?
If I went and AA'd each instance of jaggies, would it be "more" pixelart just because I went on a deeper pixel-control level?
Again, since text does not have vocal intonations, I must make sure I'm not willing to come out as aggressive, but more like willing to discuss and to better understand what exactly we're talking 'bout here :)
Its about time you start to focus on being careful with your pixel placement. You have been at it for a while and its about time for you to step it up and begin to use established pixelart techniques to express your visions. Just be patient with your pieces and be more precise. To me this is Pixelaki and not quite pixelart because of coloring techniques, or rather the lack of them.
When I said you shouldn't fret too much on this one, I was completely frank, because, as I said, I don't care so much about this piece. You don't owe me apologies of any kind at all :)
I did feel we should bring the discussion to the table, tough, because...well I'm reluctant because I don't really want to start yet another discussion, but okay. If you get too bored, or think it's way too much, feel free to say so.
But I guess the whole looking for form, lines and angles thing might be misleading. Paul Robertson controversial Birthday Cake vs Present Dog comes to me as just as much pixel art as this piece was.
Ok, this piece was deffo worst. I never tought this piece here was a good piece. However, that never stopped other works for getting in (I guess Losing It is as bad or even worse). What stopped this from being on the gallery was "careful pixel placement and lack of colour techniques". While birthday cake vs present dog has a more pixely aesthetic to it, I guess he was about just as uncareful as I was when handling colours. I guess thick works might suffer from the same problem.
About lines and form, I still think it was just a choice of mine to work with them that way.At the time, I had been drawing more and more with pastel chalks and chunky charcoals and I felt I just couldn't take pencils anymore because they need a lot more movements to cover the decisions of line, weight and messyness I could do easier with charcoal. That same feeling start to appear when trying to do "crispy" pixel art, but that does not mean I didn't think and plan through the picture. I just didn't want to go there and refine every little bit of it - just as I didn't when I held a pencil. Maybe at that given time, I shouldn't have tried to pixel if I felt that way, but I still think of it more as loose pixel art than oekaki.
These days I've being a lot with pens. Maybe now I would have enough patience to go back to pixel art. Tough I still prefer suggestions over details.
Sorry for my lack of eloquency, I just got home and am tired as fuck. That all being said, I want to reinforce I have no hard feelings at all: I do think pixel art is more than what PJ brands so, I do think thick's work should receive more respect and I do agree with many of the points that ptoing's been bringing to the table - but that's not personal at all and I don't feel butthurt about it either. I never felt offended and never intended to offend, and I hope I could convey that :)
