In the threesome art - I love the blond's hair (I want to touch it. *nods*). Is that Draco? The tilt of Harry's head is lovely, and if fact, I adore the positions of all three men. I don't really know anything about art, but the blurry image is really cool. Great job!
In the desk sex art - I love, love, love, that the boys aren't horribly skinny (I like a little heavier man myself). The possessiveness that each of them shows is HAWT! I can't begin to imagine how long it took you to draw such a detailed background. Wow!
