kk, I'm in class... French is amazingly easier to sit through when I have a project =^.^=
Here are some pictures:::
This is unchanged just to show how the eyes are too low based on the horizontal center line of the head.
This is the change I would propose. The following is a profile pic. I think you could accomplish this through a lot of sanding ^_^ But, you wouldn't have to try and move the eyes. The eye position would still be a little low... but nowhere like the original. Profile::
Actual heads (I looked around the classroom to confirm this) are higher in the back than the front. So... I would recommend sanding and reshaping.
Also... there's one other little thing that would be a pain to fix... I think you could leave it as it, but it would be something the watch for in the future. Here's a pic:
The white lines show the distance between the eyes and side of head. The rule of thumb is that the head is 5 eye widths wide. One on each side of the eye, then an eye, a width between them, an eye, then an eye width. Obviously there is not enough distance on the sides. And it looks like there is slightly too much distance between. However, I think you can get away with leaving this as is. I just thought I should point it out.
Even though I've pointed out some flaws, don't get yourself down. As you can see with the lines on it, it is very clear that you have great symmetry. And I think your features are REALLY well sculpted! I hope this helps.
