Morgana art (and in game art)

Personally i love the morgana art (i just think she should be a bit more fat (10 lb or somethink) but any way

My question is should the on game model have biger boobs ? (there dont think i just want biger boobs but on her i think it a must) (i just think if they want new low size breast they just have to make them (like jinx).

Well may be it just that the model is old. And sorry for the bad english.
