pixel art is all about full control of the pixel placement.

if the pixel art loses the sense of the importance of the pixels which construct it, then I don't think it can be called pixel art. It is when the pixels hold importance to the nature of the work which defines it as pixelart.

if you paid attention to the individual placement of the vast majority of the pixels in your piece, then it's pixel art
even simpler pixel art pieces aren't very controlled due to the artists' inexperience with how pixel clusters work together.
Just because someone is using only the pencil tool in ms paint it doesn't mean they're minding their pixel placements as much as they should or could

I looked around for this rule. Couldn't find it (unless I'm over-looking something)

It has to be clean. It's one of our rules here. Don't just drag the mouse around, place each pixel by hand, one at a time.

We have very strict rules are about what goes into the gallery, no oekaki drawings of any kind!

Erm, It is only pencil tool, and since its still pixel work, I do not think it has to be clean.

No, not each piece at a time, each pixel at a time. No spraycan tools, no shortcuts. Pencil tool only, and one pixel at a time. (Single clicks from your mouse. No sqiggly lines of any kind. Clean. Straight. Precise.)

Really?

You want me to add each one seperate..That is..well.. a lot of them..Seems wasteful...

One pixel at a time. You're getting a rarely seen 'no' from me.
