Colour Photoshop projects

Currently gettingh used to Photoshop in my Multimedia module in Applied Psychology.
Our first ''assignment'' (unofficially) was to colour an object, a person so to speak, and put them on a background. More importantly, make it look proffesh =D

 So, I took this ''Barren Explosion'' photo- which I must say is one of the most exciting photo's I've layed my eyes on, and used is as my background,

I said for the person I'd use someone I had an interest in. I chose Famke Jameson, better known as Phoenix from the X-men trilogy/ franchise.
And here is the result, many layers later......

I wanted to emphasize the explosion so I blurred out the surrounding landscape and darkened it to a degree. The hardest part usually for me is trying to make the person seem like they're in the actual background, and not just thrown on top of it, with ridiculous confusing light sources coming from all angles. So I out two light sources on Phoenix: 1: Her front. to highlight her to an extend and portray lighting shining from behind the viewer. 2: Her hair. I overlayed red/yellow to portray the gravity of the explosion in the background and its blinding  light.
