Nice coloring and composition, Your image could be improved with more work on the environment, there isn't much happening here to compliment the piece. You might not need to add too much, but something simple to help balance the colors and lighting would significantly compliment your piece. It's clear to me that you really challenged yourself with this piece, you're trying various advanced techniques which are really hard to get right, and while some areas aren't perfect, the ambition and care taken bring it to a level of which you should be proud. Overall you've done well, thanks for sharing and keep it up!
