The effort wasn't there
100% of the animation was tweened badly. The positions were awkward and the impossible. If you had spent more time on touch ups it would be much better; it's not like you have a set date for it considering it's the first. The whole flash doesn't have a plot either. Maybe it you spent more time thickening the script instead of being lazy. Over all the effort wasn't there. The only constructive thing I can say is i'd recommend setting standards for yourself so you don't end up posting something like this.
