Perhaps the rules changed between when that was posted 8 years ago, and these days that wouldn't be accepted, or maybe syosa's work got accepted because they're syosa and not a pleb like us xP
PJ's rules with regard to what counts as pixel art have definitely become more restrictive since the site's beginnings, so perhaps the WIP rule was also added later as the site got bigger.
oops, I inspired by this->http://pixeljoint.com/pixelart/47940.htm so I thought it is ok if it include finished sprites. I'll change it to finished only :) And thx to tell me what I missed lol.
WIP animations aren't allowed in the gallery (see rule 2 on the submission page). You can include it in the description, but the actual uploaded animation should just be the finished idle animation.
It looks good though! Reads quite well. I suggest adding some shadow on her forehead like you have in the preview image though, currently her skin and hair blend together a little.
great!!!
