Great job. But I liked some of your recent works more though.
There are some effects that are bit random and messy.
The dragon upwards is a nice touch as background but the background should have remain dark-blue as it blended better with the render. The light background is what causes some of the C4D's effects messy as it doesn't go with it in any way.
I'll give you 7.5/10.
You did improved though over the use of that render since you made this though.

Still room for improvement though...
