I like the 3rd one, it's a little hard to see the render except for his head. The 2nd one is a little to bright in my opinion. Great work though killer-rapz !
The text on all of them needs work. I like the scanner light like thing in the first one, that's a neat effect. But depth needs some work, and maybe a few more filters on them, as well as some colouring work.
monotone use color balance buddy ur over doin the background with to many effects tryin to hard to blend the image start with a render and work the bg from the render that way it blends well at the end
