It was a story
As this was your first flash, I would have to say that I thought it was alright. It seems like there really could have been some more color. It was kind of weird to see the dog become brown but have only the outlines of his body become brown. I do have to give you credit for having a really cool title that perfectly fits the cartoon. The animation was not that great, but you can certainly improve from there. Just work on your coloring and animation effects and with a few more jokes, you could make great work!
