My Formal Penguin T-Shirt design is now complete and available on t-shirts on Amazon. The design has been renamed Cool Style Penguins reflecting the penguin's own cool style and the cool style of the t-shirt wearer.
In part one of this two part post series I included a video documenting the development of the design in my sketchbook. It's a 20 minute video in which you see and hear me talk about each development sketch as I work toward a final design drawing.
It's not essential to watch that video before watching the video below. In part two I created a speed draw that takes you from the very first sketch to the finished design on a t-shirt in just over ten minutes. Along the way I talk a little bit about the process.

Also available is my Crocodile Rock t-shirts, as well as another new t-shirt design, titled Australian Wild Life, featuring my Australian Animals Inktober artwork from day 26 of Inktober 2017.
