lose the purple color :) and add somthing more like the render

You should lose the 2nd faded render. Also focus more around the render so it fits in with the surrounding. Other than that it was alright

Doing it now, I think this one looks better,

That one is a bit better, the typo is horrible (no offense) and there is no light source. Try blending the sig, diff gradient maps, copy the render and smudge it and things like that.
Go search for some tutorials on depth, it's not that hard.
About the lightning, create a new layer, use a big white soft brush then brush the side (do NOT overdo it) and change the blending mode to screen, soft light, something like that and play around the with the opacity (maybe 30-70% will do). After that click Ctrl+Alt+Shift+E and go to filters->Render->Lightning effects, set the mode to spotlight and use that kind of circle to adjust it to where the light comes from and change the blending mode of that layer to some that you can tell the difference in the lightning and play around the opacity.
PS: Done all of this with my head, maybe some names will be incorrect because I don't have PS opened... The blending modes are much like personal preference.
I recommend you go check some tuts on typo, lightning and depth
