ARGHHHHH
DavyDov, how could you do that? The scenery looked great, with some nice music, making us think something very artistic was in store for us. But you end with a meme? It's not even good use of meme either. There are people out there who have a zero tolerance policy for this sort of thing. Why did the meteor come back? Why did the record scratch come late?
And considering this animation is 2 megabytes in size, I'm fairly dissappointed. You need to learn how to properly execute jokes. Your theme is "how the dinosaurs died". There's a lot of things you could do with that concept! Something obsurd like the Nazis wiping them out, or something unexpected like the scene abruptly ending with "Old age...duh" spelt in large letters. I really think you should try again. And remember. Making your own objects and images cuts back a lot on the final product, as opposed to using bitmaps.
