I was wondering where you've been! Haven't seen any posts from you for ages man. Welcome back

I really like the Halo one, looks really cool. Simple background fits, but the white lines on the right are a bit distracting. Nice text though. Yeah, the render quality of #2 is poop =P I wouldn't have used it. I like the rest of your stuff mate, looks really nice. Tad too bright on #5 but other than that, it looks awesome.

Love the background of your tags, they look really nice.
