Great submission, hope you win! 
I love the little details in the background like the clouds and birds… did you add those in an image editor?
Thanks!!! 
the background is an imported image, some clouds are simple plane with alpha texture and others details are applied in post production with Gimp
Very interesting! I love the tree!
Congratulations!!!
Very creative work and the atmosphere is amazing

Nice texture and colors is beautiful…Very well made…Wish You luck in the contest…
