Ah, Random Girl Art. Nothing more fun than drawing pretty girls.
And these ALWAYS pop into my brain, just before I'm about to sleep at night. Concepts begging me to draw them before they fade from memory. So I have to get up and draw them, before I forget.
This one was of a 50's pinup girl, in goggles, changing a tire.
Not sure why it's sexy. Probably because of either the tomboyish-ness or innuendo possibilities.
