When I’m trying to brainstorm and develop new ideas I usually just start with a page like this. I’ll just begin drawing faces until they start to “speak” to me (not literally). It’s like people watching–you’ll see an interesting person and you can’t help but imagine their life and their story. After I come across a interesting character on my page I’ll begin to extrapolate environments and worlds and so on from there. If it’s a good idea it’ll just snowball from there. A lot of the time I’ll hit a dead end and then run across the notes months later and be able to come at it again with a fresh point of view. Some of my favorite ideas have developed that way.
I’ll give the coffee shop another shot in the next week and post any sketches I do here.
