ooh, i'm so sorry, I guess i still don't get the line between oekaki and pixel art even after reading the rules! can you explain it to me?
mmm, I guess these are a bit unpolished, is the point? like, more of a thumbnail than a finished piece, is that the problem?
either way i'm sorry that i didn't follow the rules! i'd be glad to reupload this correctly!!
This is some nice stuff.
I REALLY, really love the upper-rightmost picture, and would have you consider re-submitting that one as a standalone piece, because as it stands I don't think this as a whole should be accepted into the gallery, most of it is too rough/unrefined, like oekaki.
But that's just my opinion.
Usually there is a certain level of refinement in pixel peices that are approved to the gallery. Your pictures looked nice, but weren't finished enough imo.

The motto the site usually follows is 'control over every pixel placed', which means after sketchign stuff you should go in and begin to clean stuff up and details manually.
This doesn't mean your piece has to have a lot of details or anything, but it should be clean and polished.
Good luck!
