That is pretty neat. The idea behind it seems like a good way to train on just sketching poses.

oh yeah we had alot of practices - we got just one minute, or 3 minutes to draw each time she did a pose. Annoying since there was a lot of good details I wanted to get down on the paper XD

Yeah watching most artists like yourself that love details like shading and lighting effects that being limited to a small time frame could be frustrating. Kind of like telling a car guy (like myself) he can only pick one car part to talk about in one minute.

Ah, but there is a purpose to the minute sketches, they train you to focus on the essentials first, the proportions, the layout. What good is a beautifully rendered arm if it's out of proportion to the rest of the person, or gorgeous eyes set grotesquely far apart?

This also trains you in being able to sketch from real life, instead of just posed models. A minute sketch will work as a visual 'notebook' so you can later look at it and remember the subject that inspired it, and from that sketch, you can jog your memory of 'Oh yes, the eyes were like that' and so on...

I've been practicing this during breaks at work, sitting in my car, cranking out quick sketches of that stupid owl statue on the roof, the one that is supposed to scare away birds. Every day a few more sketches, every day, a different angle, based on where i could park, and I'm still learning things about that stupid statue.

hehe .... i like the left one better ...

still they all look nice

God I hated doing that in school, drawing with my non-dominant hand
same with doing blind contours. That stuff where you draw without looking at the paper
why why WHY do they do that

hehe yeah, I guess we gonna do that next week. It's kinda funny, I get really retarded drawings what else use it has, I dunno yet.
