I love the Evangelion ones...that's the new pilot!!!*squeal* All look pretty good, except the 2nd and 4th from the second line, since those look low quality. .... As for the sigs. I think the first one is nice, though it seems a tad bland, and there's depth in there, but way too blurry...I think that a little lighting and some smudging on the focal point would be nice. The second one looks like you took a night vision camera and took the pic. I think it's fine overall, but something doesn't sit right with it...I just can't pinpoint it.
I think all of the avatars are really good. Try something new with them, possibly add some effects/gradients to them in order to make them look a bit more interesting. Other than that, good job with those. As for the sigs, in the first one I really like how the blue is highlighted off of his armor. The one effect that you have that is green just seems a little displaced. Like Breakeven said, add some smudging on focal point to accent it a bit more and draw more attention to it. On the second one, the green looks like it fits his facial expression since he looks afraid and the "night-vision goggles" green color for some reason just works for me. Get rid of some the the black empty space on the top right corner and add in some gradients with other shades of green and you'll be set. Great job overall on all of these. (:
