The background looks a little plain and is very consistent across the entire piece, try to very it slightly as you go then you can draw focus to a certain point in the wallpaper. The render really should be the focus, 99 times out of a 100 so I'd try to avoid obscuring the face. With focus in mind the text is too big as it draws the eye away from the render, typography can be very difficult so keeping it mostly simple can be a good idea.

Lastly don't feel you need to cover every inch of space with something, empty space can be very effective as well so don't be afraid to use it.

Keep it going!

as original? said, you don't have to put a lot in there to cover it up, the simple and clean style often look at least as good as the complicated ones, if not better
bg is very plain and looks a bit boring cuz of that, try to add depth to it (one way to do this is to blend in a stock).. just experiment with stocks (they often look best desaturated and on low opacity) and textures (look good both in original colors and desaturated, try different layer modes).. brushes can also be used, but keep them simple then, don't overdo it
colors could be a lot better, you want the whole piece of art to blend well and look "complete", and then you always have to make the bg colors match the render colors.. in this case the color isn't the best and it is very monotone, it should also be darker..
with that said you need to lighten up the render he has dark colored clothes and shoes and it's overall a dark render, so you have to work on the lighting to liven it up.. experiment with some simple but nice effects to make it more eye catching and make it stand out from the rest, but again don't overdo it and always remember to blend the render, if you need help on that have a look at our tutorials
text is ok but you can easily make it look better, change the font to a more simple one cuz of the simple style on this wall (we've got some great ones in our resources section) and try a different color
in my opinion it would also look a lot better without those grainy dots brushes or whatever it is

hope this helps you out a bit
