Kaiju: Arctic Wolves

I've always been a fan of wolves! These animals are so majestic and magnificent,
Not to mention how powerful and mystical looking they are.

Anyway I had this idea the other day of creating a pack of Kaiju-like wolfs, to give my lonely OC Slierus so company.
And so I started drawing and experimenting with all sorts of designs and ideas, and this are the final four.
I'm not sure exactly what I'll make of it, but I would really love to know what you people think of it (especially wolves and Kaiju fans).
So pleas comment
