Quoting lone wolf
This looks really good! The leg design is very Rahkshi-like (I wish the originals were like that). And although the spine pokes up a little too much in the back, it looks perfect from the front.
Let me just say that you were the one who inspired me to make my first rahkshi revamp, guurahk, with your kurahk revamp. Your awesome, and thanks for the comment!
Pretty interesting recreation. For the most part, it does look like a mutant Turahk, except for two things -- the crossed over Mahri tubes would work as bandoliers on a soldier MOC, but not really for a Rahkshi creature. The second thing is that the back spike connection doesn't really look natural, but then again the angled shape of the spikes makes working with them difficult, and it's really only an issue in the back view.
