Did some relaxed sketching with a friend yesterday, so here's some stuff to make everyone else look better.
I should probably do this more often if I ever want to get competent at this.
The left is whatever; The right is a non-serious pokemon evolution chain based on mantises where butterflies somehow got added in as well.
A little more serious, this a mech thing that I had an idea for for a while. The shading on the actual sketch looks slightly better.
