stephen hawking's cakse

This was my attempt ( due to lack of money and resources its poor ) at making a cake in the shape of stephen hawking o.o i looked all over google for a cake similar style to go from but alas! google failed me.

This is meant to be him on his wheelchair, how ever after setting in the fridge it then just looked like a pervy old lady on a recliner with her legs spread o.o woe is me ;-;
