Heyyyy!! Nice shading and tone-work!!! The style,...oddly enough,...reminds me of some old Japanese prints I've seen!
Neat!
In fact,..that reminds me.... The earlier commentary about "ballsack" size and such makes me think of a particular site a friend sent to me recently having to do with old Japanese prints having to do with Tanuki (raccoon dog spirits), and showing them using their magically-transformed scrotums to perform all sorts of amazing functions! It's really humorous! Apparently this is one of their more commonly-known spiritual powers!! Odd, eh? Check it out!
