Definitely a fine idea and a nice execution, however as above mentioned the sunrays appear oddly to me. Aside from what thedeathhunterxx mentioned, the rightbound rays are actually oddly angled. For those rays to be accurate, I believe the sun would have to appear below its current position. Also, the mere scale of the sun makes it quite unrealistic, and not in a cool surreal way sadly. Apologies, but I have no suggestions on how to deal with everything I just mentioned, these are just ideas that filled my head as I viewed your terrain.
