Okay-ish, but please don't use brackets in signatures! They may be okay ingame, as we're limited to text there, but brackets (especially those) kill the looks of a signature.
Apart from that, I liked your more abstract approach on the Angels better.

I don't really like the combination of photo and comic (the wings) here. Also, the text above the wings should be moved somewhere else, so it doesn't divert the viewer's eyes. Your render needs to be cut out a tad better (see the version where it's on the left) so it doesn't stand out too much. Also, the bracket thing.

The best one out of those, in my opinion. A very good start for a nice sig.
Use less space here - 230px vertical is huge on these forums! Fill the background with a few more details - doesn't have to be much, just so it ain't that empty.
Maybe use another font (go here: www.dafont.com) as this one's visible in most (all?) of your signature. As well, make the text a tad more visible - but really only a tiny bit. Move it down towards the corner or outside the borders so it doesn't divert the view on the picture.
