I know very little about animation or stuff... so I can't rate this sig fairly... In terms of style and what I think, 7/10, but don't take my crit seriously, since I have no idea about the work you put into it.
avearge: 7.5/10 fav sig: the 2 middle ones are very good, i love the tech border the bottom middle sig, good job
@mango 8.5/10 - pretty cool vector, the details in the middle is a nice touch 6/10 - bit bland and definetly missing something, that or size down the canvas abit
I love the background and the render in the first, but the outerglow on it all throws it all off. 6/10 The second one is basic but good, 7/10
