Train Track Pad Sketches

Recently, I've been using the trackpad on my Mac Book to try and create some little thumbnail compositions while I ride the train home. Its both incredibly frustrating and very interesting. I'm constantly struggling to do what I want to do, but at the same time just being very minimal with the design and shapes has also been a lot of fun.

These are done in Photoshop CC and typically take 20-40 minutes.
