Feedback for that delicious Sniper on Heavy action:
1 - Sniper's face in profile does not look like it's proportioned correctly. This is probably due to the lack of shading, but in general the structure of the face still seems rather poorly defined such that there's no distinctive "front" to the Sniper's face.
1a - Please emphasize Sniper's underbite.
1b - Sniper's ear looks too high, and the back of his skull too round.
2 - Hoovy's manry manjaw of manriness pleases me, but it might be a bit too square in your rendition.
2b - Ditto Sniper's.
3 - Heavy's hand on Sniper doesn't look like it's interacting with Sniper's body at all. My suggestion is to have Sniper's arm on top and Heavy's hand a bit further back so that his fingers are just barely curling around Sniper's waist.
4 - Both Heavy and Sniper's lower legs look too short. Heavy's left (our right) knee should probably also be pointed more towards the "camera".
4a - The mattress should have more obvious sagging to show weight.
