That is a very cool dragon, I like the more orangey colour scheme
How big is he? Wondering if he would work with 10mm, but looks like he might be rather large?
If the model shown as a scale is not completely off the „normal“ Khurasan scale, it should be roughly the height of a 10mm GW Ogre.
So yes, the dragon would be huge. Roughly Dragon Age: Origins size, not the ridiculous Joan of Arc size.
Back to topic: I like this one a lot.
