This is a cute character, but there seem to be some problems with the file. I don't think it was properly indexed, because there's a total of 411 colors, and 342 of those are "partially transparent". This website usually doesn't allow pixel art with partially transparent pixels, because they usually indicate that non-pixel art tools or techniques were used.
Try making a palette at the start of a drawing and only use colors from that palette to avoid things like partially transparent pixels.
Want to give some dough back to all those amazing pixel artists? Donations provide prize money for contests, help cover hosting costs and support new initiatives.
