Sorry, couldn't really give a name to the head.
Before saying anything, remember this is like my third head.
But comment please.

and

Oh and, I am not finished, I really want you guys how I could improve it.

Nice top, and maybe you could try to add more details to the face, also make it 512x512. 7/10

And, I'm done with 512x512.
Still have to adjust eyes and mouth and add details to face.

Face:

Top:

it's pretty basic, add more details like highlights to the eyes, and make the hate more like cloth, pretty decent overal.

also, 1000th post.

Added Glasses and did a few changes:

Also, should the colour stay yellow or should I set it to white?

EDIT:
I recolered it white, fits better, oh and I added hair. Can more people comment it?

make it a re head and call in ginger boy lol

But all i see is that maybe work on the teeth and maybe add a tung.

Add some more stuff to it, it's really simple right now. Throw on some shadows and highlights to make it look more 3D, because right now it's looking pretty bland (even with all the color)

Simple is good,I like it the way it is in face,8/10

Did a few changes:

I try my best :S.
Also, I am using Paint.net. And I really don't know how to do some stuff you guys suggested.. ._.

Download Gimp or Photoshop,they are MUCH better.
