redditors portraits

I discovered a sub-Reddit called Reddit Gets Drawn not too long ago and find it to be a great source for drawing models. I've been using mostly markers to create them and I'm starting to really like working with markers. I've been told I draw like a designer. TouchĂ©!

will mankind destroy itself?

This is my second sketchnote project based on a speech by Michio Kaku. It's very interesting. I'm really happy with it.
