Modelling shapes without reference images/image planes

[Anonymous]

Hi all,

I have recently embarked upon a mission to model a bunch of creatures and objects from the doctor who universe (or whoniverse, if you prefer). I have successfully recreated several of these creatures, but ran head first into a brick wall with the weeping angels, specifically the head/face.

Here's a picture of the head:

I want to know if any of you can give me advice on modelling such shapes as the head (with the facial expression) without any images online of a high enough resolution or of a good angle for use as an image plane. Is it possible that there's a way to create image planes in photoshop?

Thanks for any help!
