This Belongs To You

there's a lot to go over here, so i'll take it by steps.

1: The Eyes

You've made Blue and Green's eyes solid color, forgetting or ignoring such details as the pupils and other things.

also, Blue's eye contains a few spots. i assume that those are light reflected in her eyes. this is possible, though implausible, given the degree, though most would overlook that.

Green's eye, however, also contain, which Is impossible.

2: The Hair
This part is definitely the best thing in the drawing.

the subtle nuance-difference makes it clear where his hair ends, and her begins.

the only remotely odd thing is, that her hair seems to be going under her shirt.

3: Her Hand

as has already been pointed out, her hand is highly similar to a claw, which is odd, because nails don't grow into that shape.

i'll assume artist's error.

4: Her Boobs
i know, perverted. ^_^

unlike the manga, You've given her a shirt, that exposes a bit of cleavage. Which is By no Means, a Bad thing.

though, it must be said, that said cleavage has a somewhat odd shape.
