It's a good start.
Yes, I think for your first flash ever, you can hold you head up high.
But there are many points on which you could improve.
Foremost, loading. Why load a 3 minute audio clip for a 30 second animation? It increases the file size necessarily and therefore means the pre-loading takes that much longer, which in some cases raises the expectation of the submission.
In this case I'm afraid it did the opposite, it left me disappointed. I wanted to see more, if that makes sense.
It's a good visual style, if a little choppy.
And the lack of a story just meant I couldn't give this more than 5/10.
But you're halfway there, to making very successful flashes. I wish you all the luck you need, but I'm sure if you stick at this, you'll succeed.
