@RS, your minifigures get those annoying white specks on them too? Glad to know that mine aren't unique in that ability.
The frame is ok, but the white background is a little odd. It's like he's leaving the Haunted Forest and about to enter the "White Expanse of Doom." (Not that the forest looks haunted, it just sounded cool.) Something doesn't look quite right with only the minifigure in focus, but that's just my opinion. I recommend adding some more rocks to hide the white paper, and then some vegetation on the ground to make it more "Wild outdoors-y." Right now it almost seems like a city park with the evenly spaced (Or almost so) rocks, and nothing on the ground save a few tiny rocks. The LURP's could also do with some slopes on them to make it appear more like unhewn stone.
