Be patient!
I was close to blaming, but this is why i chose not to: It actually has a preloader, it has a play, back , replay and fwd buttons, it does not loop over and over again, there is sound, the birds are very well animated and its much better than the average first flashes that we see around. There is mayor differences in QA from the background, to the birds and to the main guy, my main suggestion would be to be patient, and take your time, idea wise you have or seem to have lots of potential, give your self time to actually develop those ideas and deliver something closer to what you really imagined. keep it up!
