I hate when that happens...
Santa Clause caving in because of Fatkins and all that... Santa's fat and immortal. It doesn't get any better, dammit!
Anyway, this is not bad for someone who hasn't been creating flash for long. Some of the animation was pretty simplistic, but it got the point across. It wasn't as good as the other one (that I saw a while back), but that was done by someone with a lot more experience.
You did kinda lack backgrounds, but that's normal for a newbie. Lining backgrounds up with characters is painfully tedious and usually looks terrible the first few times you try it.
You should (based on viewing your earlier work) improve with time. You might consider either creating a script or getting a friend to bounce ideas with. Having something solid to work toward (as opposed to just kinda making something as needed) forces you to come up with ways to accomplish the things you're brainstorming. Then it's a matter of seeking out tutorials and then going through the tedious process of implimenting what you've learned.
One final bit of advice - get into some art classes and get a scanner to import your drawings/images for tracing (or get a tablet if you can afford it). You can only do the simplistic characters for so long before people figure it out and start giving you low scores because of it.
