As I'd discussed with yndaaa, modeling an item ordinarily seen on the super round face of an anime styled piece onto the square head of the blockhead is ridiculously difficult. He gave me some good advice though and i'll probably work on it later.
While that is true, what you made is far easier than some other stuff. THAT IS BECAUSE: It can be separated into easy to identify components. Take something, for instance, a stahl helm. That would be really hard to model, because it is all one piece.
Do eet.
Also, your model is really flat... And in the last picture, the bevel is wrong lol.
