I had the same experience with Kenny he is hands down the best and all around great guy!This guy changed my life. I believe he has some videos but you can do 1 on 1 Skype sessions with him. Shelby recommended him to me and It took my posing from shit to being told I was the best poser at my first ever show this fall.
