I really like the chosen colours, the contrast of heat to cold is conveyed nicely. What I think you could work on is the anatomy of the bird wings, I would recommend looking up references of that online. I am also a great fan of the background, the far mountains and the sky look really nice.
Overall nice work ^^

I am a big fan of this face, the way the fire casts light and creates shadows is really effective. I like the cold hair color complementing the fire in the background. His mouth is very big, but not so much that it could not be realistic, it just stands out.
What i think looks a bit wierd is the shape of his upper body, gravity seems to do strange things to his clothes.
Love the drawing style, looks a lot like where I am trying to go right now.

I really like the shape of the body and the dress, her face looks a bit off tho. All in all good work.
