well...
well let me start off by saying you have done an excellent job on the backgrounds, they are really nicely textured, and the colour scheme of them fits together really well... your style is quite... unique, i like the messyness of it, well to a point at least, but the flow of the animation didnt seem very interesting, but i guess if you were pressed for time, i guess that is why. the sound, well it sounds like you've got a £3 mic and are in a barn of some kind... the ambient noises, well they were just sort of out of place, unless the noises were suggesting the movement of the mechs flying around... well the "look what he did to the pug" bit made me laugh, but overall the story was quite lacking... who? what? where? how?, just seemed far too slapped together and if this is for a project, they'll probably mark against you for that, the "story" didnt seem very structured and therefore takes interest away from it...
oh and also add a proloader, ppl on dial-up will hate you otherwise :P
