I add less or more structure of muscle tone and weight ratio which varies, and I also change the chin and or jaw which creates an alternate look. I also change hair and eye colour, freckles, good skin or blemished skin and scenes which again change the look of my creation, altering scenes also creates an alternate look. Also I use butterflies and flowers in much of my art representing myself. I put more work and more layers into some pieces than others it all depends on my capacity of vision at the time, how well I am and how fresh or exhausted I feel as to the end result. If my work looks like AI I will take that as a compliment, but I have a program uniquely designed for me from the society for the blind and it is not AI! (one day I hope to share here on renderosity without having to explain myself on every piece or collection!)
