Only just noticed the PM you sent me dude, they're looking pretty nice. I like the lighting used on the Forrest one, but I do agree with one of the earlier comments regarding the background, that could do with abit of work. The Semtex one has a nice feel too, but there is a little bit too much empty space. They're a good starting point though. I'd advise checking out a few online tutorials to give you some PS tips, I know it really helped me out when I was starting. It's good fun just tinkering with images and playing around with designs, I'll be interested to see what you come up with!
