CC: Too big, Light sources are off

^What he said^
Also try blending the render with the background.
The colors are off and remove the text until you get better.

I wish i knew what all this meant, and how to do it :lol:

The colors are way too different.
"Blending" means making so that the renders seems part of the background

Is there something in photoshop i can use to create this effect? lol

You could start by changing some of the colors on the render, you can also place some fractals or c4ds on the sides so it blends

i think it looks pretty nice for a first . bottom right thing needs to go, colors could blend better (match better - create a flow of colors that go with each other and complement one another). is a little large... try focusing the size around your render. i.e. not all of your render has to show; you really don't need that much of his back showing and etc.

also google c4d renders and find some nice ones that could help blend your man into the background instead of dropping us straight off from his bright white/grey suite into the dark black background.

This is all just CnC from users who have worked in photoshop quite a bit - don't take anything personal, i still like your signature and think its not half bad!

Thanks! =D
I'm gonna put a few hours into improving it right now

or you could even just start making new ones, it's always good to improve but sometimes it's easier to start over.. post your results!
