your current robinho sig is very nice, i like the colors and lighting work a lot

good bg and the 10 is nicely blended in, simple but nice render effects and overall good blending!
text could be a bit better, but overall a very good sig!
your earlier sigs are all a bit too busy, and the effects are a bit overdone.. so, good improvement from those and to your current one!
as mufc said, your ava's are generally too blurred, but the mourinho and kanye ones are nice. work on the contrasts and they will all be a lot better!
