Blast from the Past #694: Sketchbook page 39, Ideas for fifth Turtle?

On page 39 of the sketchbook, I drew these rough sketches of what I think are some ideas for a slightly different facial look for the proposed "fifth Turtle"... including what appears to be either a tattoo or some kind of face paint in one image.

I also noticed on this page that I drew the "fifth Turtle" with three fingers and a thumb, as opposed to the classic TMNT look of TWO fingers and a thumb. And looking back at the previous page, I see that I did the same thing with this more finished drawing of the "fifth Turtle". I didn't notice that when I posted it yesterday. -- PL
