I took my workshop students there to sketch yesterday. This is my demo page created in an 8.5x11 Stillman and Birn Alpha journal.
Bald Cypress trees remind me of dancing ladies, their wide trunks looking like hoop skirts. The tree on the right and the Spanish Moss were painted with a large round Pentel waterbrush. I find that if I load the brush with pigment, then touch the brush to a Bounty paper towel to get excess moisture off, I can achieve a dry brush effect. The pen sketching was done with a sepia colored 005 Micron pen.
Here is a short video about the wetland.
