I like the fact that the neck and limbs are so long, it gives it a cool abstract vibe while maintaining the solid colors and feel that is in, it's very compatible with the background :D
the top of his hair is a bit odd but i like the hair from about the nose down. I especially like the two striped bits of it that are going down over his neck and shoulders i like how not all of it has those blue highlights, the face- especially the overly pointy chin.... could be better but i like the color of his iris and how the pupil is a slit.
Other things i like include his cool black nails and the way despite the fact that his expression is kinda annoying- like he's looking down on you or something (><) he still has some sense of elongated elegance to him.
The symbols in the background are also cool, work on the face and in terms of the top of the hair it looks a bit like a rushed version of generic anime hair i think it would have been better if it stayed straight all the way up without the spikes at the top sticking out with only one fringe to the side maybe with that having a few spikes instead of the for want of a nicer word mess around his head.
i like it though so i try harder next time k!
looking 4ward 2 more of ur stuff

Her neck is very long, and she is far too slim. Makes her look quite creepy.

Good, but his neck is creepin' me out.
