Your style of doing it is good, but i found a few problems. Little seam at the back. the sides doesn't look good and the hat seems to be floating on top of the head.
and the flat that you posted doesn't have the shadow of the hat at the front :O
Ooooooh I see the seam now
I don't get the floating part though xD
The silver is connected to the black
But idk how it is floating O.o
Lolwut, dat flat.
But I assure you it has the shadow I just put the wrong flat xD
