I love it, great mood.

Nice. The fire and the shading is very well done. 

Adding some Emeralds in the rock formation could look good.

 thanks guskooyman :) the light grey is supposed to be snow so rocks on the ground could work I guess .... I started this for the weekly challenge but then I felt green emerald would spoil the general atmosphere... so I'm out of the challenge

This is very cool. It reminds me of an old fantasy game, or lord of the rings. The glow of the fire looks nice on the trees, but I think you should have added some rocks on the ground to reflect light.

Also, I see you used the weekly challenge template. I don't know if this is for the challenge, but don't forget that you need to use the color emerald (#009774).
