the dragons just look like toys, which starts to make everything else look like toys, and then the effect is ruined. Nice lighting though on the non-dragon items.
Interesting concept. For a still life, however, you need to get the focus and DoF right - the dragon appears to be out. Highlights on skull appear to be blown. Heavy shadows on the coins. I might have tried shooting with softer light (putting some cloth between the light and subject) and using contrast control to get the drama back.
