They're pretty decent heads... My only issue is that all 3 of them look incredibly similar.

Btw.. How are these realistic? (Actually curious, not trolling)

If you download it and open it in gimp/photoshop.... You can see the face being realistic, ut the eyes aren't realistic.... What I mean by realistic is the shading and the face shape....
Like this:

lower the water mark and yah but it looks relatively good id put a little more shading on the nose but yah its good i guess for the eyes i made a tut today (if u have photoshop) not sure if itll work too well on gimp but hers a link ) http://forum.toribash.com/showthread...64#post4239364

Actually for me it looks like 2 stange shaped eyes and 3-4 darker tone lines. Its not realistic

In my opinion, you should modify the darker lines and let more space between the lines and the eyes. It will improve the "realism"

i dont understand why its called realistic..... the shades are not realistic the mouth is not really realistic 2/10
make the shades a little bid biger and use more colors
