Your colour scheme is great, it gives the mini a very "reptilian" flair. The scales are a great freehand job, but I alos like the claw-like toes. Great paintjob!
Great piece! I like the freehand scales on the armour, the blue targeter, and the hydras on the chest plates. Very well done. The metallics could use a bit more definition, but the overall effect is nice. I'm working on one of these models myself right now; they're a treat to paint, eh?
