Other video games, TV shows, movies, general chit-chat...this is an all-purpose off-topic board where you can talk about anything that doesn't have its own dedicated section.
Biggest thing for you is some contrast and colour variance.
Go to layers-->adjustment layers-->colour balance and mess with some settings there (make sure to adjust them in midtones, shadows, and highlights.) From the same menu you can add a 'Curves' layer. Make it's shape a slight S-curve and it will really make the image pop. The design seems to be there for you, just get the techincal side down.
I really like it , save two things. One, the PHX logo doesn't really fit there, I think either make it bigger or drop it completely; two, there's something missing on the left side, it looks empty, but I can't think of what to put there.
I've already told some people that I don't have time to make request signatures (which is true) so if i went out of my way to make you one, it would be a bit rude to the other people who have asked.
If I get some time to make signatures for other people, I"ll post it here, but i dont believe that will happen till after AP testing
