I'm taking intermediate anatomy and college math in the fall,because no student loan money for summer available,I'm spending my summer reviewing the anatomy and practicing quick sketches of people at the library and outside restraunts,I would like to put down one definite line and be accurate,for the sake of speed that is what I'm practising for,portraits are my main goal even if its just on the street corner.By the way you were exactly right when you said my martial arts designs reminded you of 70s and early 80's,I designed and printed them on t-shirts during that period for different schools and fund raisers.Thanks for lending an ear,its always good to talk to another artist.
