I love the clean, cartoony style too, and the piece has lots of character! The mutton chops are a nice touch.
To my eyes, the right leg looks a little bandy since the thigh appears to be the same distance from us as the left one, but then it curves round to the foot. If this look was intentional then that's all good, but I've done a small edit where I've changed the angle of the thigh and the top of the shin a bit to straighten out the bones. It's not polished, but hopefully it's illustrative.

I wonder if the torso could take a bit more shading too. At the moment there are creases on the T-shirt, but not much of a sense of the shape of the body underneath. The left shoulder and arm are in shadow, but the torso looks more like it's facing us.
Overall, it's a really nice piece though!
