Nothing to do with vivid imagination

Your right it really is just a graphic of two dragons, I'm sure the suggestiveness of the image is purely unintentional. Advertising agencies on the other hand do it on purpose, you don't usually notice it, but it definitely sells products, Camel Cigarettes is the first to come to mind.
I prefer beer ads with chicks wrestling in a water fountain....that's my kind of ad, blatant and up front
Kona....I showed it to my wife, Psych, Human Behavior, Criminal Justice in college, she says that by just showing the two dragon heads and necks....it looks very much phallic, kind of like just showing the barrel of a gun. She suggested just using one dragon and showing more of its body to remove the symbolism. She also found the colors suggestive too, but I don't see that.
BTW seriously....nice job on your first bootskin....I haven't even come close to creating anything worthy of submitting yet
