It needs a lot more contrast and light. Isolate the important elements and attract the focus to them. Are there characters in this? I can't see...
Hey, good on you for attempting the December prompt.
I would agree with Tom, everything is kind of blending together so it's really hard to tell what is going on. It seems that your focal point might be in the center of the image? If that's so, I would suggest bringing a lot more contrast with your values to that area so that we can get a better sense of what's going on there. You might also consider making your character a bit bigger so as to stand out a little more?
As it is right now, I would say the first thing my eye sees is the smoke to the left of your character, then they sun in the right top corner, and finally the rocks on the bottom of the page.
Overall, good start and I look forward to seeing what you submit for the challenge this month.
