Dragon Lake Valley

It's been a long time since I drew something original. My gallery's been saturated with fanart recently and I thought it's time for  some original work.  
This is my 2nd time doing a landscape themed painting and this was the best I could do, although there are places I can improve. Wanted to keep this semi-realistic but with a paintery feel. The idea is that the valley is protected by dragons. Birds with translucent wings fly across the sky. Some dragons live in the lakes and heat the springs above. 
Hope you enjoy!
Thank you for all the visits/faves/comments/watches till now.
