Awesome. I feel like I'm slowly getting the rules. I know I should probably ask somewhere else, or consult a FAQ, but do you know how long it usually takes for pieces to get approved? I have another one uploaded that I think follows guidelines, but it's been awaiting approval for a while. I can't tell if I should make changes. Thanks so much for your clarifying things for me :)

np. good image and colors btw, just not right for this site. to quote alex hw:

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.

So dragging the pencil tool to form lines or playing it fast and loose with such a large canvas will generally mean the placement of the individual pixels isn't all that important and they could easily be adjusted with no major effect on the image.

Oh cool, I haven't heard of Oekaki. Thank you, it's good to learn more.

I'd definitely say this is more oekaki than pixel art. Bit too sketchy/uncontrolled for the gallery.

Interesting concept, but it could be a little more refined and less "sketchy."  It might be beneficial to work at a smaller resolution.
