Hey , really nice stuff. Sounds like an ambitious project but man are you putting the time and effort in. really like all the creatures.
On some of the characters, you need to watch your proportions. On the character wielding the hammer; his arms and legs don't quite match and you've forced the hands and feet into uncomfortable positions. I know those finer details are'nt really going to effect project. But for future work, it might be something you want to look out for whilst you work.
Keep up the great work, would be nice to see some sketches and wip if you have any.
