That's strange. Just upload a new piece, now you have a work with a bunch of irrelevant comments.

also needs AA

@greenraven: yes absoluty diferent piece, I change for other :-)

Call me crazy but isn't this whole conversation about a completely different piece? O_O

@ ultimaodin: Look, everyone has their own learning process, and their way of doing things, I honestly do not my forte pixelarts with many colors, and here I see more than 40 colors. Criticizing for criticizing That is fine, but that I am apprentice not mean it's stupid, sorry to upset you the way in which this is done, the next I try harder, glad you already?

You can't just further lower the colour count (now at 252) and try and get away with it. Guess what, the preview's still the same at 555 colours. It's still yuk, it's still messy and now you're lying through your teeth. I gave you a chance to confess so that you could ask forgiveness and follow the rules of Pixeljoint and continue learning the pixelart craft. I'm going to leave this to the mods but now you're blatantly trying to cover your tracks with further reductions. Also, the only editing I see you've done here by hand is the background.

Whatever, it's up to the mods now.

 I sometimes resize paintings, reduce the number of colors on them, then clean it up until its pixel art.

the difference is that I use my own work, I have 20-30 colors instead of thousands, and I do much more clean up than you've done here (honestly it looks like almost 0 clean up here). Also I'm transparent about my process. 

Process is mostly irrelvant when it comes to deciding what is and isn't pixel art, it's the final product that counts. And this final product is extremely messy, not to mention someone else's original artwork.

 Make pixels from scatch. What is the point in editing pictures? There's no effort or creativity in this, even if it wasn't a color reduction...

@ultimaodin: Right now I do not see the problem you speak of, I edited completely pixelated image and I think it has less colors than say

You edited 5875 colours? The problem is it looks bad and looks like a colour reduction. Reducing the colours of something then moving a few pixels is not considered acceptable for gallery submissions. Grabbing an existing piece, making it smaller and then moving a few pixels is considered art theft - especially since you didn't post a reference. At 5875 colours, even if you did make it by hand it would never get accepted. I think the largest colour count to be accepted is 256 and those have to look hand pixelled and clean. This does not look hand pixelled and doesn't look clean.
In a PJ gallery submission it has to be your own work. Else wise it is simmilar to a photo manipulation which Pixeljoint does not allow. Especially not without reference.

I'm telling this so you can admit to it and not do it again. I know your new to the site so I don't want to straight up report you.

I don't think it's such a big deal, you just made the mistake of not posting the original piece. It's the same with music in my country, you'r allowed to take sound samples of up to 5 seconds from other songs, as long as you give credit to the original artist / composer. Anything longer you would need permission and you would probably have to pay for it.

Well, if it is true that simply used a capture on film sci-fi: 'Wild Planet' 35th Anniversary, and I edited by hand. Other than that, what is the problem, I've spent a good time editing and pixelizated.

Considering there is 5875 colours in this - I'm going to have to go with this being a colour reduction, especially considering your gallery so far. I'm not sure why you would do this, you don't learn anything from doing it and it's considered theft. I definitely recommend you come clean about this. If you admit to it and actually show effort on improving as an actual artist then many people will forgive you, but honestly grabbing an image and colour reducing it teaches you nothing.

I give credit to MikauKahn for actually finding that image.

It looks like he just shrunk down this picture. I'm not sure where the colors came from, but I think it's fairly obvious that this isn't pixel art.

How did you make this piece?
