I think goodbye is mistaken and that this is just fine right here. Anyways it's a good drawing. The stripe on the face looks strangely like an offcenter mouth though, so maybe having a small line for a mouth would make it more clear that's a stripe there.

goodbye also draws pixel art, so her saying something is pixel art probably shouldn't be interpreted as a bad thing.

the reason this could be considered pixel art is because of the lack of antialiasing and smooth shading, and the relatively small scale of the picture.

edit: ahh, okay, I get what you're saying now.

I was just saying that there isn't a "pixel art board," but a sprites and icons one (which includes pixel art but there's other things there too, not all icons are pixel art) and that the description of that says it's intermediate level and that beginner level art should still go on the beginner board. Also I was just about to edit my first comment to be less harsh
