...wee bit of honesty.
I've worked with all the programs you have listed.
I like how you meshed the transitions... but in reality - each form of animation you displayed lacked true detail - well of course the photo you took of the trees.
As a game modder, your 3D stuff could have been better. As an artist, your pencil/(wacom?) skills are a bit lacking.
But all in all, it was presented well - and in the real world, that's all that counts. But as a critic, I'm an asshole. Don't worry, you'll have a chance at revenge soon when I finish a similar cartoon.
Flash/Fireworks/Final Cut Studio/Logic/Maya - (for animation concepts only)
Great job and good luck!
