Siridar said:One thing though. You should give the character a shadow. It'll ground him in the picture instead of making it look like he's just floating there.
Do try to keep your light sources consistent though! The mountains and trees in the background indicate the sun is somewhere to the right. The shadow you drew indicates a light source from behind the left shoulder of the viewer.
Any shadow is better than no shadow, but it'll look even better if it's consistent with the rest of the picture.
You could also try shading the figure itself. Add some highlights on the right side of his face (your right, not his right), darken the left side of his hair, torso and sleeves.
Overall, nice work though!
