[AMIS]

I dislike going over more than three abilities...it`s not unheard of but it tends to make 1 unit overpowered. I know you can always increase the points but the army tends to need to revolve around that unit instead of that unit fitting into that army. Not something I look to do in my customs. Long way to say that if you like the Wild Reach skill (which I happen to do) you may want to drop the Dzu-Teh Enhancement. Wild reach is more unique and Enhancement is more an overused Orcish ability.

The smaller figure; I can see the Glacier Traverse and enhanced movement but you could also use a pure bonding (perhaps wild bonding) to let it keep up with the Dzu-Teh, Rhotaga and any other wild character out there. Because it's smaller, but still a hero how about something like:
Life 4
Move 5
Range 1
Attack 3
Defense 4

The attack of 3 shows it's smaller (if really a lot smaller go with 2) but the defense shows how tough a smaller figure needs to be to survive that climate (it also replaces camouflage but this reason is thematically better).
