Animal Practice

Practiced drawing various animal headshots to de-stress a bit ;o;
most of these i draw in like 5 minutes and look like trash lmao
but i kinda liked a few so

I would really appreciate any critiques/advice/tips on any of these drawings!

OH I used this website for ref images for all of these btw- artists.pixelovely.com/
It's a really nice website to practice drawing different things and I love it a lot

To , I'd just like help with over-all anatomy. A few of these animals I've never really drawn before, and I'm going for a semi-realism look, so any anatomy help would be much appreciated!!
