I delivered a sketchbook skool art session a while back - on 'busy drawings'.
How do you get lots of ideas in to your composition quickly? - in this case an urban scene.
Make a list of objects for your chosen scene - I suggest 50 - cut them up - place them in a hat - choose them randomly - draw whatever comes out of the hat until they're all used up.
See the list I used below
Try to make your drawing make pictoral sense. Play with scale and placement.
Complete your drawing in 20-30 minutes.
Felt tips / marker pens work well for this exercise.
Ps Kids love this drawing game.
