Great portrait, she has a very good level of detail. Reminds me a lot of "Rosie the Riviter". Although I'm partial to this one because I am a mechanic, and have a lot of surgical steel in my own left leg. Although I don't smoke cigars, heh.
Nice pose, and an interesting balancing of details.
It's interesting how one shoulder is protected, and one hand gloved. Does she use the wrench as a weapon... or fixing large dangerous steam driven machinery? Also, what is in her pouch?
