doesn't feel finished to me tbh. It feels like a great start though, but if this were my own piece this is probably what I'd call the half-way point, where the tablet sketching is over and it's time to get down to the nitty-gritty of arranging individual pixels.
Really needs some softening up and blending. I again agree with Celia.
Love the idea and the pose, it could just use a good deal of refining. It looks like a basic sketch or color blocking for a piece, to me. Pixel art is about controlling the pixels, and I think this piece lacks that control. It is definitely a great start though, I would love to see it polished up and finished.
I agree with cure, but this is a really skillful piece and I hope you finish it.
