Warg Riders

To offset the cavalry component of a good army, the bad guys only really have Warg Riders until later in the book (film).

I've tried to retain some of the 'mane' on some thinking the flat featureless backs rather poor.

Perhaps Lilliput applied would improve things?

I tried for the look of the area round the deer park in Queenstown where they ambushed the refugees on their way to Helm's Deep.

Again I think manufactured rocks are an improvement on the real thing.
