Wip - need help about anatomy

I'm working on a MTG card called "Trained Caracal" art by James Ryman, but i'm not happy about the anatomy, but i'm not sure about what to do, if I try to pose first or keep trying to improve before posing.
Thank you in advance

Original art by James Ryman:

A little update
I need to improve the paws, I'll keep working on it.

just a upgrade, not finished yet, I still need to fix the paws, and maybe the head, cause it's looking a little big to the body

after fixing this problems I'm going to paint/set a good material for the mask and other golden parts

Well, here is the "final form"
