Test design Bowl

Saw this being made on a video a friend sent to me. My first attempt, It was a fail but I know my errors, Once I perfect this design they are going to be awesome :). Im liking the optical illusion idea for bowls. And since I am fluent in AutoCAD. I am going to try other designs. This bowl is scrap but I know people that appreciate even my failed bowls :) Its claimed already :)
