I do recommend that:
1) Your credits be moved to the bottom of the page. The font might not need to be so big either...
2) Move the "Darkness is my only friend" line to somewhere near the top of the page and center it. Also, the font could be bigger.
3) The colours you've used for the central character is quite bright. Maybe use some darker tones and overlay a black to white gradient to make the character blend in more with the background, since she's supposed to be a part of the 'darkness'. (My impression anyway). Or maybe use a grayscale palette...
4) I don't know what you have planned, but maybe a hint as to the next page, a panel maybe of background or action or something, around the bottom of the page could help. It might also make the transition smoother. But honestly, it could work out without this depending on your next page.
I can't really say much about your art now, but it could always get better. Any errors with anatomy didn't stand out too much, so that's always good by my books.
Do what you will with this comment, but it's just my two cents. :/
