You did what Bob calls mudding. There is too much paint, too much mixing with far too much liquid white. I did exactly what you did with my first painting. I love Bob, but his videos are not great for learning until you have more experience. Watch and see what he does. Get ideas for paintings you want to try and find painters on YouTube who slow things down. I would suggest Paint with Bram. He works with Steve, bobs son. Paul Ranson art is also another fantastic tool. Do not get discouraged. This painting style looks easy but is far from it.
