Research before the sculpt

I browsed the internet for research on sculpting i found a few cool images that interested me here are a few of them.
In this picture below i really like the wrinkles they sculpted in it gives a realistic effect on the viewer and the lips and chin have a reasonable form to them.

 Below in this Abraham Lincon sculpt i like how the sculptor exaggerated around the eyes to show a deep eye socket.

 In this picture below are a few head sculpts which show a well done neck, it shows a lot of the muscles and a few veins located around the neck too.

In this picture below it shows opposite sides of the face, it also shows a well defined jaw line and chin.
I will not be using the facial expression because its does not appeal to me. But on the other hand it has an accurate structure of the ear.

In this picture i am planning to sculpt this type of facial expression, i like the crease around the mouth it is very defined and i think will be fun to sculpt. Also the brow gives it an angry look to it which again will be fun to sculpt to see how i will be able to pull this off. The zygomatic bone (cheek bone) is shown well when pulling this facial expression so i do want to show a lot of the form so in this expression it hits a lot of criteria i would like to hit.

In this picture above resembles a face which shows all the muscles i will need to understand how to sculpt it into my own.
In this picture below it shows more of the facial muscles that i will add to my sculpt.

In these two the picture above it shows the neck muscles and i also had to understand them to again put the sternocleidomastoid muscle and show a good form and understanding of anatomy. The sternocleidomastoid is a very prominent muscle and is very visible. In this picture below it shows the face spread with faces, edges and vertices.

Above is a block out of a nose for sculpting, it shows the basic sub division and what i will need to sculpt it into.
