Maybe put the woman up on a rock or something to bring her in closer to the dragon...maybe put her on a low cliff with the fire on the floor, and give her a torch/staff for some light. Also the sky looks more like rain than evening...how about some last bit of sun or a touch of pink in the clouds. I really like this image a lot! I'm not sure it needs more light, but maybe just more contrast.

Fractals will always amaze me!
