Nice work! I'm a graphic designer too… proving it is a small world… The yellow is very effective here (and I'm damn impressed if it printed in CMYK ) -- Great use of the leprechaun theme without being cliched. Plus you can actually read the darned thing… I just hate posters that are beautiful, but unreadable. Here you have the best of both worlds -- Attractive and intriguing, colors that draw the viewer in, an appropriate theme and something that let's folks know what and where.
