Haha, very creative.
Positive : Original idea, I like it. THe birds were drawn neatly and the background was drawn nicely. The signs were very clear, nice, easy time to read the text in them in. The words on the menu, when they wiggled, was my favorite part. xD Overall 8.
Negative : It got a tiny bit repetative, but still, the song comensated for that. Maybe add colour into the background?
I quite like it, especially for a first. The AS was quite good, better than me, atleast. :D
