Next assignment, facial expressions

For the next assignment i have to do 8 facial expreshions for a charicter. ive decided to do a new charicter, if i were to use an old one i wold have to make 12 diferent faces.

my character is going to be a steam punk type who is an older man and a doctor, he is suffering from a sickness that requires him to weir a suit so he can breath a chemical to stay alive. i got the idea from them deep sea diving suits that make you breath the liquid air stuff so you wouldn't be crushed.
