thats a pretty flat eye for a realistic head..

Oh yeah lol. Thanks, ill fix that

This head is pretty decent for start.

Can you post watermarked flat? I'd love to see your proportions as I'm trying to learn them myself!

Add more shading to the scarf/mask by varying colors. There is no shading under the nose for example, on the mask. There is no edge to it either. You can also shade the mouth under it.

Add different skin toning to the skin aswell.

Try to put shading with gradients on the schlera, and then try to color the iris.

nice hair

The hair is fantastic, however I think some shading underneath the bandana needs to be added. And also, the source of light seems to be coming from like four different directions. If the light source is at around his forehead or from high above, the shadows need to shade in the correct direction. Aside from that it looks like a well made head so far!

Thanks guys! I probably should have put on here that this a wip lol. I still need to add more details and shading. Final product should be done soon. Thanks everyone!
