Cute portrait For the reasons QueenKami has mentioned, I'll put this piece in revision for now. You can edit the piece to resubmit it, and I'm looking forward to adding this and your other pieces to PixelJoint's gallery!

It looks nice! You can use the thumbnail as an avatar if you'd like, just click the little person shaped icon under the art!

However, as with another piece you have, you should upload a 1:1 of this image, rather than a zoomed in version. There's also a few dark blue pixels in the word bubble that you could probably remove. There also seems to be some compression going on here or something, causing artifacting which is making your color count go WAY up. I'd double check it and try to resave it and make sure the colors are more consistent.
Here's this one as well, for reference :)
