In Fall, the company I work for, Ocean Treasures, was hired to install and maintain the planted aquariums at a new Conservatory of Flowers exhibit called, The Are of Aquascaping. On top of being the lead aquarist on the job, I also got hired to illustrate not only the exhibit signage but also a collectible art poster and other merchandise to be sold in the Conservatory gift shop while the exhibit is showing (Dec 14 - April 15, 2014).
This poster (above) was a beastly drawing! 4' long, 18" high. The prints are coming in any day. You can see a higher res one under "wildlife illustration" under the scientific Illustration gallery linked from the top of the page.
The Conservatory gift shop also has mugs, glasses, and shirts, all drawn by yours truly!
