Sounds about right.

After reading through the Drizzt books and the War of the spider series, Rothé are just the underdark version of the standard farm cow for me. That and that there should be relativly few underdark druids (lore-wise) make the choice a pretty strange one. A Ram or dire Ram would have fitted better and have the same mechanics.
For a hommage to Drizzt a black panther would have been better :P.

Also the Idea of basic shapes + choices on hitting the appropriate level sounnd really awesome to me. Individuality is a big part of RPGs for me.
