Not bad
Not really too bad, lacking in plot but that's probably because you didn't actually plan on doing anything with it from the beginning. You've got good enough flash skills to make a good, memorable flash if you come up with a good plot and put the same effort as this into it. The only thing I would tell you that you actually need to work on is the way you have him walk down the steps, it looks like he's floating or something. You gotta make one foot step in front of the other ( at least that's what it seems like you're missing..) Good luck on your next projects.
