i really like how you've reanimated the classic scene where freaky fred grabbed courage the cowardly dog...
you've drawn freaky fred in a scarier, more deranged way (which is quite accurate), and you've drawn courage the dog perfectly, while showing his horrified face expression nicely, combined with the contrast of fred's insane look in his eyes.
apart from the good design of the main characters, and of their perfect face expressions, your animation was swift, fluid and very smooth (with a nice flow+speed).
was the whole animation FBF, or tweens?
it had a great pace, and i liked its FPS speed. (was it 30 FPS?)
either way, great work, nice design, and a very smooth animation in general.
you should make a fan-made ''courage'' episode or two, that would've been a great cartoon/tribute, considering your good animation skills....
anyway, i liked it alot, so keep up the good work!
