Pen and ink watercolor effect

Saw this effect on Pbase a couple years ago.

I am digging for images right now to use with the new Scott Kelby Seven Point System book. I picked up a copy on Friday and flipped through it (looks interesting). I am hoping to be able to get into the meat of it this week. With that said, I will more then likely be posting older images I have taken this week so I can dedicate time to get through the book. If there are any images that take on a drastic new look from doing the tutorials, I will post them.
