I can see that I need to make the background wider on the right hand side. And my One True Love says the eyes are too blue. I will think upon it. Obviously, it's not a realism issue, but is a graphic issue. Soft green might be prettier.…Also, I don't think the orange patch in the right side ear is right, so that'll come out too. It's so easy to edit! Please jump in with suggestions at any time!
This is the picture I've used (kind of) in the colouring in. I should have used it as my original sketching references, it's a pretty little kitten and mine's a bit grumpy.
