Looks like a really good start!
I really like the detail on the thundertusk. the teeth and bone on the howdah look fantastically layered and the fur on the ttusk is very nicely done.
constructive criticism: the ironguts have a very good scheme with vibrant colors and a good aesthetic, I'm not sure if the pictures don't do it justice, or if it is such a subtle shading that a camera can't bring it to life but I think another layer or shading could really bring the skin tones alive, from the picture they look rather uniform.
Same thing for the golds on them.
Keep up the good work! keep on gnobloggin!
