The volume in those clouds... really lovely stuff!

The clouds rendering is superb. The character not so much. Some AA and probably less saturated colors on the clothes would make it blend in better with the background. The animation, albeit a bit stiff, adds to the scene, and that bird passing by from time to time is an excellent little detail! Nice job 

Very impressive and atmospheric

thanks, yes of course, the 2x version was not intentional.

Nice work! Can you please post an unscaled version? Thank you!
