I don't want to criticise, But i'm going to. Carry on as you are. you're new to this, I'd say really tone down the lighting that yellow looks like someone pissed over the scene, What is this in the foreground by the way. Looks a bit like a stray cropped image ya plonked in there.
So that's just a couple of things to criticise about, CONSTRUCTIVE! Don't take it the wrong way of course. everyone learns from mistakes and such and improve upon their prior work. :) Keep at it buddy
EDIT: Oh it's a concrete barrier... it obscures the screen quite a bit
