3 Sketchbook drawings 15 minutes each.
Draw what you want, but TRY to make them FINISHED drawings.
You can use whatever materials you wish.
If you have a hard time thinking of something that you WANT to draw,
think of all of the excersizes or projects we have done in class e.g.
collage, boxes, basic solids etc.
Try to stay on the drawing for 15 minutes without distractions, See how far you can get.
Also try to apply method to your drawing like Andrew Loomis' Five C's.
