Becoming a Renaissance man...woman

No, I'm not quite a draughtsman or much of a scientist for that matter (unless you call my crazy food experiments in the kitchen a scientific inquiry) but I am taking a drawing course to improve my skills. Reason? Well, I think that learning to see the difference in value (the lightness or darkness of color) is a good skill to have in photography.
I may never be as great as Da Vinci or Picasso but it's fun to try anyway.
