i really like the second one, with the contrast between the two sides, and the third one has some nice coloring and the blending is also great with the same person in the bg except bigger.
and the first one was your entry in the sig contest i see...

i actually really like the bg effect, and the text in the corner, although you could have blended the image a little better, it looks kind of sloppy and edgy, otherwise really nice effect, and as a whole it's also okay, but the other two are alot better.
(oh and as a more insignificant note, the "To" in hazzards request should have been in white, or at least a bright color, had i not known it was there before, i wouldn't have seen it at all...)
