Very well done! I have auditioned for some cooking sows and make it as a semi-finalist on MasterChef (didn't make it on the show, but I was an alternate on call".. Couple of suggestions....they associate producers care nothing about the editing. They want raw footage to see that the video hasn't been sliced and diced to meet your criteria. Keep the big/joyful attitude! This is the reason why you will be selected over your cooking. Your story is great and they love that!
Have a blast if you get on and the best of luck!!
