Aww thankee You're too sweet. It really is a challenge to try and convey something quickly. I recommend it to any artist - to set a time limit and keep trying to take less time on each piece...
Definitely. I remember when I took art lessons many years ago, we took 30 or 60 second sketches of a model who constantly changed pose to sort of get more confident with the strokes and to get used to the human form. It was a very good exercise.
My big focus these days is speed. Trying to get pages done faster and faster...Time is money!
Back to my grindstone!
