This is over contrasted. The white in the text and some of the stock work is blending in but is too bright. I can see there are some effects on the text more towards the right hand side which would stand out more and add more dynamic if you were to lower the contrast on the text. (It sort of gradients to a grey tone)
The text is nice, wouldn't usually flow but in this case works.
Maybe remove some of the effects over his face and body to let the render stand out more.
I do like the use of stock work, maybe blend it in better but there are really cool effects going on here. The quality loos lower but if you change it up and make it look higher quality (cleaing up the render) it will look a lot better. The colours between the red and cyan don't really usually work well together but in this case it works. I like this, really want to see a V2!
