I just finished up a run as Isengard. Challenging faction, but with some sweet looking units!
One thing that struck me as a bit inconsistent though, was the warg riders.
The current Isengard ones feature rawhide and fur uniforms with bony spikes. This doesn't fit with the blackened iron industrial aesthetic from the movies.
I think the current riders should be switched to Gundabad, where they would fit in with the rough mountain 'bones and skins' look.
I figure warg riders in Isengard would be getting their gear from the same forges and assembly lines as the rest of the troops, so would look pretty similar.
Here is an attempt at putting together a more consistent skin for the white hand dog boys.
Thoughts and/or suggestions?
