Re: Ghost Recon Sig.
Not bad at all. But here's a vital tip that you might want to find useful: try using as many render-based colours for your backgrounds as much as possible. That way, it blends even better. You can use the colour-picker tool for easy selection (but I guess you know that already).
Beside that, good work. Especially the text. I always find it troublesome to put my text at the right place, personally.
