Good job, clever composition, though I wouldn't recommend uploading two versions of the same image with only a small change to the lighting. In my mind it would need to be a fairly drastic difference to merit a separate upload. That aside you've done well - 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. Keep up the good work and thanks for sharing :)
