Illustration Friday - Tattoo

This picture was a tattoo that I designed for a friend of mine. The placement of the tattoo is on his outside left calf. The concept and original drawing was his idea (if I can locate that drawing, I'll post it), but I refined the idea into what you see here - I also added color as the tattoo was done in black and grey to match a different one that he had done on the other side.
Although the tattoo itself looks good, I'm not sure that it translated very well to skin. Not being a tattoo artist myself, I was not familiar with the intricacies and requirements of tattooing enough to guide my design and the amount of detail involved in the piece really needed to have the final tattoo be larger than what it was to capture the detail.
My favorite part of the design are the tribal-like markings on the 'mermaids'' lower halves which continue up their backs and onto their heads.
Anyway, enough talk and enjoy the picture.
