remember that everyone has a unique style, take some time developing yours :D

my only recommendations were:
longer snout (for canines, felines have a short snout)
thicker neck
also a bit of a thinner snout, though that could just be my style owo;
try using basic shapes!

and I put a little bit of blue lines on my redline to show some recommendations :3

please don't feel as if you need to copy or listen to anything/everything I say! as said before everyone has their own style, this is just mine :3
take all the redlines into consideration and choose what advice you like!
