(I’ll be critiquing your cats, I’m not very good to ask about human anatomy.)

When I first joined WCO, my traditional art was good, but if you look far enough in my albums, I was pretty bad at digital art, as I had just gotten my drawing tablet.
So, here is a personal favorite by apofiss. Amazing artist, btw.
In the tutorial, it demonstrates how much better art can be when you improve a bit on lighting.
For you, I personally would say that the lighting is relatively good and the only problem is the shading and color blending.
For shading, like Cas said, if you would settle on a good midtone value, it should turn out alright. Example: Choose a palette of flat colors you like, and decide which would be your cat’s base coat. Then, draw out your Lineart and fill in whatever that color would be in. Then, add highlights, going with the fur, and add shadows, going with the fur.
I recently got into lineless art as I feel it can show a description of fur very well, but I also can say that a lot of artists use Lineart in fantastic ways, so that would only be my preference.
I drew an example here* of flat colors, etc.
*Yes I know my hand writing on digital is crap X3
Now, I can see you’re going for a more... Lineart-eee type? Those steps can also be used, except add the highlights and shadows where the fur tufts in the lines are.
Another thing about colors, when markings are on a cat, they are normally blended in with the colors around it or atleast more hairy looking. Blend those in a bit and it should look fine!
Now, I personally think the eyes are pretty good, I definitely don’t have much to say about them except adding a bit more than four colors (Shadow, main color, black for pupil, white for highlight) will give it that extra kick it needs. I’ve recently been experimenting in my art, and I found that even with cartoon or Lineart styles you can make something stunning.
You did ask about the back leg on the cat on the branch?
I think you having it up on the wood is a good idea, but for the cat itself to fit completely on the branch, the back paw would have to be under it’s stomach, which is okay to do because my fat cat does it everyday.
Or, you could have it hang down because that would also work, but I like that only one paw is down.

Sorry I wrote you a book! I actually found that I like your art style, and that the anatomy of the cats are pretty spot on! That’s something I can’t exactly say for some of my drawings, :3, so I commend you on that.
I know that the reference sheet I drew you above might not fit the Lineart type of shading, so would I have your permission to show you what I mean on one of your artworks, preferably the cat headshot?
If not, that’s fine, I can probably scribble a Lineart down somewhere to give you an example.
