It's good. The first thing I would address is to make the contrast between the man and the doll more extreme. Make the guy into more of a badass gangster, perhaps. Something "cool." I'm sure it will show up much better once you add color, and the doll is all frilly and pink, or something. As it is, it took me a minute to understand the reasoning behind his actions and expressions.
Yep, deffo a scrap, but a solid start. There really isn't much to most animation besides filling in the tweens. I'm not a genius with style myself, yet.
When I watch the openings to Thundercats, Silverhawks, or a few animes, even though the first two shows, at least, are rather stupid, their openings are so godly. I can't comprehend how they were produced, or imagine how I would extract such knowledge from them without breaking it down frame-by-frame.
