Rotate stomach to the left, move shoulders a bit more to the right, also move the neck more to the right, use nocollideworld on the gun and you're set.
Maybe pick a bit better angle, move the camera a bit futher away and to the right, catching the whole dude in to the picture. Leaving out the legs doesn't really look good imo.
Tell me more about nocollideworld good sir.

Thanks man, yeah you're right, I couldn't get the SDoF to work quite the way I wanted it to, he is a little blurry.
That's because you set the focus distance to his hand. The best way to find the proper focus that I've found is to just get it roughly in focus, render it once with the blur amount at 1, and with only 2 or 3 passes, then once it's rendered adjust the distance further or closer, render again, and just keep using trail and error until you find the perfect focus distance (or almost perfect if you aren't applying a ton of blur). Then set the blur size to whatever you'd like and the passes back to 16 or more.
