photo shop fun

so this here is an example of two things. the puppets i used to make and sell at the farmer's market in Chico, California during another lifetime about 10 years ago...and the fun you can have in photoshop! i am just trying to figure it out...half the time i am just randomly pressing buttons and hoping for the best. for instance, i could NEVER get a blue background again...i swear, my computer just started to feel sorry for all my lame attempts and just sighed and did the job herself...
