A head I have done.

Preview:

EYE dunno how to rate this maybe 5/10 kinda cartoonishhhh

The ears are great, as is the pacifier. I'm not digging the eyes, though, as well as the general shading. It's good though, so 7/10

It looks super weird, Idk I give it a 5.10.

yeha the ears are great and realistic but just about everything else isnt so it makes it look kind of weird

The ears look like they've been slapped on, try to blend the front of the ear into the head to give it a more natural look.

the eye outline is a bit sloppy. needs cleaning.

pacifier, looks upside down in my opinion, and that darkercolor on the sides of the head, look too dark, need to lower the opacity on them a bit.

nice start tho. you look like a promising artist.
