Hey guys, here are some of my recent artworks, really trying to find ways to improve so any feedback is appreciated

With this one I wanted to convey the story of this one man, lost in these peaceful mountains leaving red scarfs to track his path as he goes

With this concept, I'm trying to achieve an organic earth-like feel to the demon and convey his brutal and savage nature.

Thanks!

I think that it happens because the surface cools down at different rates.
