Nice mood, the use of light looks nice. What bothers me a bit is the river, which looks a bit too drawn while the rest is more realistic. Try to give it a bit more perspective by making the river more subtle (more tiny further away) and think about which direction it would go if it's in such mountain like landscape (perhaps you wont see all of the river because it's partly behind a mountain). The river may also look more interesting if it wont start down in the middle but maybe more from the lower right corner (so that there's also something happening on the whole right side of your image). Up to you if you want to do something about it.. Good luck!

Thanks for your comments wazowski...

I will surely work on your suggestion!

Hay wazowski,

Certainly an improvement, imo. Good luck!
