Nice work, lacking in some detail but the overall feel is well executed and smooth. 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. This piece is decent, it effectively conveys what you are trying to go for, so good work. Keep up the effort, and thanks for sharing your work with me! :)
