I tried to draw over for a bit about what I thought need some fix - but keep in mind I'm not an anatomy expert either ne =w=;;;

What I drew over:
-The girl's body is tad long, or maybe because it's so thin it makes her waist looks super long (and gotta admit that despite what I drew over, that's still a little too long >_>;;; try measuring the length of her head and x4, that's where the crotch should be) I'm not too sure about how her hips should turn out since I'm not really good with female anatomy so I might drew the hips too wide =w=;;

- Another thing about the girl, her arm is way too long as well, you see in my draw over that normally the elbow should be about the same level as the waist.

-While their faces both turning to the left(or down, duuno which to refer to for sure), yet from your original sketch, their eyes on the side they're turning to bugged out too much. The eye -should- be hidden by the the nose for a bit in case of the guy and remember, by the structure of the skull, the bone around brow area bulge out more than the eye area.

-As for the guy, his forearm was too thin especially the wrist and his hand seems a bit too big. The purple line was what I drew to see how his back should be and I guess maybe his shoulder needs to be a little wider or I should have drawn his back bulge out of the behind some more since I'm not sure which angle you're trying to pull his body in =w=a;;

That's all I can think for now ^^;;;
