Here are a few people I drew from memory. There are so many characters out there, especially roaming around Santa Monica.
The bottom sketches were done with my trusy hi-tec C... better for the minutia. But the thicker marker is nice for just "getting it down."
These are great fun. I need to do some anatomy drawing from my books to brush up on proportions; it will improve my ability to draw from memory. Oh, how I love learning about drawing. I'll be a student as long as I live.
