I am indeed impressed by them. I'm glad I've gotten to know the Haida a little bit better, thanks to your mod.
I don't think it would hurt the originality of your Haida mod to include some of the themes they would have most likely been familiar with, but didn't originate themselves.
I'm kind of surprised at the lack of a Sasquatch
He'd make a good stealthy summon, I think.
If you are going to do a specifically (or atleast regionally) Haida mod, and are concerned that the Pueblo people won't be represented, I'll be glad to help you create a Pueblo mod, and you can keep true to your vision.
