Hello Eric,
A very nice scene you have here so far. I like all the different things going on here, theres a lot to see and look at.
My only critique so far, and I think its and important one
is that the elephants just dont look very angry to me, they dont look like they are charging into battle, about to trample the enemy soldiers to death!!
When you see an elephant charging, it widens its eyes, sounds its trumpet and most important of all, it puffs its ears outwards… Maybe this an attempt to make itself look more imposing, and probably to cool its self down at the same time. The elephants in your image (while very nicely painted) just dont look very angry to me.
I would try opening those ears outwards, and also try showing the eyes widened with more of the white parts showing.
Good luck buddy…
