(I think proportions on the right are better, but maybe someone out there can give more accurate variant)
As for hand - concentrate on it's form (look at your own hand) and suggest a finger or two - when artist draws a smile, very rare he ill draw all the teeth.
I have the complete picture uploaded. But I think that is ugly!
Because the legs and left hand.
(by the way: "Her name is Laila!")
