IMHO, the Avy isn't bad. I think you should add a border around it though.
I'd give the Avy a 7.0/10. If there was a nice looking border, it'd definitely be higher.
The Sig - ew, the orange-yellow bar at the top and bottom. Those just don't look right, mixing in with the red background. The renders of the Thief and the male in Pegasus Armor are also... they just don't fit in whatsoever with the rest of your Signature. Looks like you made the background first, and then you took those two pictures, and just pasted it onto it. They just don't work well together.
2/10 for the Sig. It just doesn't look good. Sorry, man.
