That's really cool! Great character and awesome sculpting. It's really impressive!
Just one thing, your final image comes up at 1310 pixels on both sides which is too small as one of the side needs to be at least 2048 pixels. If your original image was the rigth size, it's possible that the file size was to large for the forums and got resized. If you can get it at 1mb you should be good.
