Interesting.
It has a nice feel to it. The metallic looking shading on the dragon is a unique effect.
However, there are some problems.
The first is that they eye should be farther back. It shouldn't be directly over the dragons mouth; it should back in its skull a little more.
The second is that the spikes on the back of its head look off. It feels as if they should be uniform in width and length.
Lastly, I strongly advice against using lens flares to represent anything but lens flares because it makes it look amateurish. Also, it seems to be in stark contrast with the other two styles that you have in this picture. You're already blending two styles of shading in the picture with the background and the dragon, so I think that adding a third style - the crisp lens flare - is too much.
But overall, it's not that bad. Needs work, but still, not bad. Keep working on it.
