Looks like you used the old school eGO tag for the background. I like the current one eGO uses. You could have offset the eGO logo more to the left and make it look like it was the light source for the Blops 2 guy.
I didn't notice the Citizens part of the Manchester City sig due to my viewing angle of my monitor. Probably could have made it a little darker..
Either sig are decent, you're consistent on font. dafont.com has some nice fonts if you didn't know already
