Hello everyone. I recently posted the following piece to my gallery:
http://pixeljoint.com/pixelart/127478.htm
Today I received the message that it requires revision before posting. I can revise it for sure, but first I just needed some help to understand what needs revision. Any help is very welcome! Thank you for everything in advance!

Some background: I agree that the piece is far far away from perfection (no pun intended), but recently I have been working on finishing what I work on (an obstacle that I have been having a hard time overcoming), so I have been limiting myself to a set time duration to each pixel art and I need to accept its state (this explanation is missing from the pixel art description btw ).

UPDATE: All solved.
