I understand what you mean, Zoroark is a really nice Pokemon, the shape of the muzzle is not bad, but the neck seems maybe a cbit too thin.
I like the shadowball, maybe a small blending effect would have been nice too, but I don't know if it's feasbile with pencils.
Mind the claw though, they are supposed to be in the continuity of the arm, yours seems to be added, maybe you should have made the base of the arm going a bit up on the base of the claw.
Aside that, it's not bad, keep drawing to improve ^^

Ah, thank you so much for the comment, Phendranos! I will consider the suggestions, and hopefully I can improve in the future. Thank you for the kind words, it is always appreciated! :3
