I dont know how bad you think it is. But to be honest your mesh is in a mess.
You’r having alot of triangels and loops that are “zig-zaging” along the surface.
For example thoose weird looking bumps around the eyes are for sure a combination of triangels and subsurf.
Try to make your loops to run in a more rounded and “clean” way.
There is a tut somewere called “a better face tutorial”. It will help you alot.
Now I’m not a modeling expert so how much the mesh is a mess isn’t something I know much about, that tutorial link though is great it’s what I used. What I do know a fair bit about is facial proportions and that’s also in trouble.
Aside from studying real faces which is important there’s great stuff online to help http://www.gfxartist.com/features/tutorials actually has two good resources, I especially love the Andrew Loomis book Figure Drawing for all it’s Worth. http://fineart.sk also has that book and another Drawing the Head and Hands which is wonderful.
Ah, I was actually aiming at a semi-cartoony effect in the long run, so proportions weren’t one of my major concerns, but I’ll look into it for my next try anyway.
In my experience you must know the proper proportions first before trying anything that’s only slightly stylized like what I think you were going for here. Here’s what I mean, say you were going to model one of Disney’s more realistic characters like Snow White, she’s stylized but her proportions are similar enough to real that it’s better to start with real proportions and adjust them to get what you want. If you were doing someone incredibly toony like Elmer Fudd it would be different because his proportions are no where near normal. Does that make sense?
