the middle one seems kinda random but the contrast between the two sigs with the middle one is really a spectical 9/10 really good job I like them alot but the text is hard to read.
Oooh pretty.. text in the first one is a little hard to read, and I really know nothing, I just want to know how bad someone is going to tell me my new siggy is.. so let's go with a 8/10
Avatar, awesome avatar 9/10 Sig nr1: To much brushing over the renders, like the border 7/10 Sig nr2: really good border, like the way you put the render, 8/10
both ar edecent, although they need something more. seem a little bit too one dimensional. 6.5s for both of them
