I have dedicated a notebook to these fast sketches. I used an old bullet notebook so I wouldn't feel to precious about the drawings. I have always found it really hard to sketch fast, even though it gives me pleasure and usually when I see other people do it, i like the results a lot better than painstakingly photorealistic drawings. But I find it difficult to let loose.

 

I tried portraits with ink and black pencil because that is the direction I want to go in.
