I know the rocks need work............what else? 

[Kadri]

Not much
I don't know the others but a little more contrast , just a slight crop from above

I think you should put the sun about a third from the left, but greatly reduce its power (to 1 or less). Then add a copy with full power, but disable its glow and specularity. See what happens....
