Over all of them, I give you a 8/10, I love the first one, but on the Half Life one, I don't like the way the subtext slants down.
one of the few renders on which a border like that loox good. Sig not best quality but all in all it loox good. 8/10
ZOMG nice sig man. nothing mind blowing, but a solid sig with no real weaknesses. Nice border, goes well with the sig. 7.5/10
The color on all of them is nice but what caught my eye was the brushing effects that you used. How the heck did yo get that? anyway 9/10
look for some smudg tuts and get smudg brushes. I'd recommend sticking with grunge first tho, to learn the basics. @Cuse. 6/10. monochrome and way too plain. lots of empty space around the render. @guy above me, 7/10.
