Putting together a new Demo reel soon, i wanted to take a shot at doing some realalistic human heads. My inner geek wouldnt let me go without at least trying to make it look like someone famous.

the likeness needs a lot of work 
Well thats where i need help. These are my first heads, and i know they dont look like their pictures. Im just having trouble pin pointing what it is that i need to improve.
I have (since posting the above) stretched out her face a bit. I can see that its a bit to round. I’ve also moved the lips back a bit because they appeared to be to far out. And i’ve adjusted to the nose to be a bit more Pointy.
Anything will help. I want to learn.
Well, for that there isnt much I can help with. I am crap at modeling heads. but, good luck
new work. Crits welcome. thx guyz

Are you using the default zbrush head as the base for all of these?
Id def look back on Alba’s lips, they look swolen like she got stung by a bee… lol
Practice a lot with generic faces. If you try to nail a likeness you will be worried with that and miss all the learning
i am. im using that head in the example meshes.
Updated shot of Alba…

Look at this and try to repeat process. If you will do realistic head in month, it would be better than 10 heads like yours
Sorry if my post harms you
