The sketchbook I'm using is not one of my favorites as you really can't work watercolor on the paper surface as you can true watercolor paper. This one in particular is Global Arts Handbook which I think is better suited for drawing.
F.A.S.T is the abbreviation for the name of our sketching group (Fetch a Sketch Trekkers).
I've worked this particular illustration a couple different ways trying to decide which I like better. Trying different lettering styles, different art tools, various placement of lettering versus illustration, etc.

The first one was using a piece of chalk straight out of the box and the second was after sharpening the chalk to a point.
