If you want some pointers...what you should do is learn to make your tags pop I say this, because it looks a bit flat...the background seems to overlap on top of the render as well as being behind him (which gives it that 'flat' look..what you want to do is give you render its own 'dimension' (or should i say 'that solid middle ground') If you want to practice depth just get a render and play around with some stock bgs blurr them so it looks like they're far from the render...and if there should be spots that look close to the render then leave them un blurred etc... Looking at some photography really helps...lol hopefully that helps a bit..
