Actually, the shamrock shape wasn't even planed, it just came out this way. At first I thought it looked like hearts, but I'm a bit tired of hearts right now, so the green shamrock shape seemed a better option.
While drawing this I couldn't help but think "it's be easier with vector on the computer", but damn, I want to train with *pencils*, and I'll do. :p
