Thanks for the good words Rajee & Tyklfynd.
I have used reference materials many times in
my career, but this is one I didn't. I do believe that
in a very real way the images in all the tickling venues
qualify as reference material. The fact that I have seen
these images combined with my strengths as an artist
(anatomy and facial expression) means I don't have to
have a piece of reference right in front of me because I
have it inside me. This is due to people like you openly
sharing what you like and discussing it. If I know what
you want to see, you can see it. Thanks for the feedback
and interest, I hope this answered your question and I
welcome any others you may have.
