From an animators POV
First off, let me say sorry if this turns out ot be too long.
I've been learning animation professionally from months now and all I have to say is wow. Personally, I'm not even a giant fan of the show, but this is amazing. Especially for ur age. To be completly honest, this is actually better than the majority of animation actually on the show itself! Also, currently, i see the score is about 3.3 and i don't know why. It should be at least a 4. I give Fifen's to good animation and not pure humor. If you were to do a short with this type, it would easly compete with Prowlies and littlefoot. Plus, I can tell right away how insane you must have gone with all that inbetweening, and let me say it was worth it. FINALLY, i would like to point out how well this turned out for an all flash (if im not mistaken) cartoon. TT is mostly hand drawn, but stuff like this just destroys it.

This is just amazing.
