Love the effect painting here, the use of colors in general!! It's on a small scale and you still made it absolutely readable... Very very good stuff, love it :)

The detail on the fire is quite good. On a first glance, the features are a little small to get what's going on, but the more I look at it the better it gets. 

Nice composition and use of the theme. It really feels like a scene from a fantasy setting. I like how you create a color contrast between the various parts of the image and shade them individually.

You could make the image as a whole more cohesive by blending different colors into each other by lighting or shading using dithering or some of the in-between colors from the palette.
