I have done many of these exercises before and I'm not sure if I've got my brain seeing things the right way or not yet...  

I did this exercise two or three times with different plants but there was a breeze and I couldn't get my paper to stay in one place either.  I tried!

Blind contour drawing was a laugh and I barely managed to stay on the paper!

The continuous line drawing is supposed to be of a head of broccoli, not a brain.

With the waterbrush additions does this look more like broccoli?

Going further... I tried to continuous line sketch my yard and the house next door..

And with the waterbrush addition maybe you can tell what I was drawing.  

I need a lot more practice until I can see differently with my brain!
