Ahah, you have to think that I learnt to draw this position from a similar drawing were the cat has behind legs even bigger

But my question was about the dimensions needed to see my knuffel accepted, what do you think about? I didn't know if make the top of the head high as the usual knuffel head or the top of the right ear (as I did now, under TimTam's advice)
P.S. This is the drawing that I took as model:

And I can garantuee you that if I'll succeed to do what I'm thinking about it won't really be a realistic cat...
