So I'm trying to finish this model (rather quickly) and the best way to see how its going is to get some critiques from other people.  I'm working on a Christian Bale head, and I think it looks relatively like him, but there are a few things I know are off but I can't put my finger on them.  So here is where you come in, with your fresh perspective tell me what you see/think is off. 

Its stilla work in progress, I know the hair/ears haven't been modelled out yet, I'm just trying to see what should be done to more resemble the subject.

UPDATE 2:  Added some color but its still a work in progress

UPDATE:  I'm updating the OP with the final one for now:

---------------------------------------------------------------------------------------------------------------------------------------------------------------------

Updated:

the lower pat of the head looks baboon esq! Does his chin really stick out that much?

Amazing nonetheless though, well done

From what I recall, Christian Bale isn't solid white. Hope that helps!

Thank you, and yes your right his jaw area IS sticking out too much.  I feel like it looks correct in the profile but not when straight on or at an angle.  Tweak tweak tweak.

Shit!  I'm screwed.

The tip of the nose is slightly too pronounced.
His nostrils are slightly too big, too high and too revealed/open.
His mouth is too protracted.
The chin/jaw might be slightly too protruded

His chin juts out too much.

Thank you everyone! This is great help. I'm also noticing his lips aren't defined enough, I need to go flesh those out.

You must show us your progress. You are very talented btw.

Is this done in Maya?
