At long last, here's the final version of the massive 2' x 3' poster I made for BroNYcon on September 24, 2011.
asked me to make a movie-style poster based on Celtic mythology and Scotch/Irish legends and featuring pony versions of Lauren Faust, Jayson Thiessen, and Sethisto from Equestria Daily. The main story she asked me to draw from was that of the Celt hero Cu Chulainn (Jayson) and his mentor/teacher, the lady warrior Scathach (Lauren.)
For Seth, I recommended Saint Patrick since Mr. Sethisto has done so much to bring the pony gospel to the masses.
You've also got Canterlot as Brigadoon, the Green Man as an apple tree, and some other odds and ends.
The poster was a lot of work, and working at this kind of scale was a new experience.
I hope everyone likes it! This certainly was a labor of love...and lots of Red Bull.
