I really wanted to like this one. The concept is pretty good, the music is good, the art is top notch. There are a lot of major problems though, not the least of which is the writing. The whole thing is very slow, the dialog doesn't feel natural, much of the voice acting is bad, and there's an absurd amount of filler.
You need to pick up the pace. We don't need a robot bird giving a 30 minute speech, if you must have the character trim his part down and use a faster (and intelligible) voice. We don't need such a completely uneventful traveling scene. The people reading the lines really should practice them much more (Bubsy and the woman were pretty well done), so the delivery is snappier and doesn't feel so strained. If this is supposed to be a comedy (I really can't tell), your writer needs better material.
You have something with potential on your hands, and with some (admittedly large) improvements we could see something genuinely masterful.
