The nose in the self portrait was so terribad that I looked at some photos of random people and Bridgman to try to understand them better. You can tell which nose is Mr Bridgman's, it's the one that has some proper structure!
(I'm sorry for lined paper, I need to be frugal so I use everything I have before I go and buy new things. This only for rough/quick studies and notes and such, invested drawings will get good paper)
I still don't understand noses but I will figure them out.
