[One] I like the color blending with the anime and background, I don't really like the glow on her though. Animtaion on text is a bit skippy. Really like the border.

[Two] Like the anime you used, your background is good but since it's a background you could cut a part away and it would look the same(meaning repeated background) You should work on filling more space, like your text is small you should enlarge it a bit.

[Third] I really like how this one fits. Only text size bugs me, you should make it a bit bigger. I like though that you have a background that is a picture itself so not an empty looking area.

[Fourth] The background is a little to strong brushed? I don't know how to explain that. Anyway your anime pic just is way to smooth for the background. The text is also to hard to read.

[Fifth] Your anime pic looks a little streched sideways and the background you can barely see. I like the chose of text you used but I think you should have placed it in another place.

Overall I really like your sigs gj expecially for just a few months.
