Ok pic chick..nice first post.As far as composition goes...it is pretty good. Interesting perspective, but there is not obvious subject...the bottom stuff kinda competes with the wall in the background. But overall, I think the perspective is pretty good. Note that the wall in the background is leaning slightly right....I think it would be better from a different angle.
As far as exposure goes....there are some trouble spots. The mood of the shot is generally low...since the spot you shot is in some sort of cave/hole in the ground. The sunlight shining on the top is is hard to look at after all the shadows in the main part of the frame. Maybe try to PP some of that brightness down...and brighten areas in the bottom and on the main subject. Also, some more contrast wouldn't hurt..at least on my screen.
Good job!
