I like the bottom one the most. I can't see anything in the top, and the middle although well-done, looks too much like all the other sigs here. 8/10 for the bottom one.
Your current is so bright I can't see what it is... 1/10 EDIT Someone posted before me :S The wintermanip looks really nice 9/10
1st one is excellent, 9/10 2nd one is so-so, 7/10 3rd one is bad because of text and render selection..4/10
