totally botched BUT paid for creation

I'm trying to get a fairly simple idea created and firefly is getting it incredibly wrong.  Everytime I try making changes it uses up my credits.  Shouldn't there be like a follow up correction regenerate thing for the product produced to get what I paid for?  

I have a goat cartoon image I upload as a png that I want to be used in teh creation.   I've asked that this goat walks by in the background, stops and looks towards the viewer, gives a mischievious grin, then tosses the contents of the bucket of tar seal coating material onto the screen blacking out the entire screen.  The seal coating drips off and once cleared can see the goat continuing to walk off the screen.  What I got is just ridiculous.  4 different renderings.  1 sorta got it, but the goat stayed up front, and was not the goat I uploaded, nor was it walking on two legs holding a bucket and squeegee.    I'm not exactly sure how to get it to do what I want it to do.
