Nice painting! I like the mood but i agree with Marius. Maybe more foreground and and less backround should work better. Now i feel a bit empty the middle of the picture where the focal point.
Anyway kepp up!
i like it! mood, texture work, details.
for the guy's location you painted, i'd go like this.put him on the right rock on the foreground and make a bridge between that rock and the left ones.it will stronger the composition.
