. Truly, it is an astonishing sight. I will spare you more rambling about Envy, since you're surely heard enough of that. Love the fingers in the bangs, and her expression. I think you got the mood spot-on too, with the lighting and everything. I imagine Envy gets really into her music.
(BTW, I was horribly distracted writing this by a song on Glee)
