Creature train doodles - part 1

Some pages of the sketchbook I strictly use on my daily train commute. Doodling on the train became an important method of relaxation, and while it's fairly loose, firmly planted in my comfort zone and not too focused on iterating, it keeps the "creative juices" flowing. Most of the creatures in the book are little explorations of shapes I want to translate into good designs further down the line.
