Nice
Apart from lacking plot and sound, I'd say this is pretty good for your first flash in terms of animation and I think that you are a person who will put effort in to their animation so I think you should perhaps make some other flash with a script and sound, but still I like the fact fact that you are willing to spend time on their animation unlike some who just skip frames. Overall (considering 1st time circumstances) well done, continue, I see the makings of a good flash animator here.
