here's a few tips for further practice: 1. the ears don't just melt into the head, there are over lapping bits, refer to some of my anims for an example. 2. try not to draw your eyes so overly large, unless that's just your style. If so, keep drawing them like that. Also, add pupils to your irises if possible. It'll look more realistic. 3. your anatomy could use some work but it's actually pretty good! Though, try to reduce the curves in the bridge between the head and the snout unless you're drawing a cat, which do have a very steep curve in the bridge. 4. your poses are actually really good, but once again the anatomy needs work, you should be able to see the other back leg in the sitting posed one. 5. last but not least, your lines are a little scratchy and the 'fur spikes' are a little too big to be realistic, though I know it's easier to draw them so big. Otherwise, looking good! I hope my tips help you!
