Plume illustrations style guide

Hello friends ?? Here is the result of a multi-month project that I started. We were lucky to find?Fred, a very talented illustrator. We considered probably around ten different directions. After many back-and-forths and input from all of the team, we arrived at the initial set of illustrations. At this point, I wrote a draft of the style guide definition. The illustration set grew for another 3-4 months and a couple of new visual treatments came forth. Recently, the project was mature enough to create a more precise and robust style guide definition. Please let us know what do you think!
