The jump pack is from Kromlech, but it looks like one of the old Raptor which are my favorite style.

The legs are chopped up Fenris Wolf legs, and the extra glare from the shiny blood does make them look kinda blobby on camera. Looking at it on my desk, his feet and fur is a little better defined in person.
I just got in some wulfen legs, but even they seem too short for the size of this fella. I liked the length of the proper wolf legs, and they really made the line of action work for his loping pose.
