Well, it's not really a Tutorial like the last one, but I think that can help you !
The best to do when you want to draw cats, it's to.. look at you cat ! You have to begin by drawing me, like I did, with a semi-squeleton like theses ones. If you don't have cats, Google is your friends, just look at some pictures you can find ! It would be really helpfull. 'u'
How, by the way, you can use these sketchs as bases if you want, you don't have to ask for it ! However, I'll enjoy to see your drawings. ♥
