Loved the energy efficient light bulb.

yeh , to me making cartoons is also a new thing :) but it was an amazing experience

Well, not bad actually. I bet you know by yourself what are the points on which you have to work more, so I would not insist on criticize your work. I am shure that it was great experience and a lot of fun :) so keep going with that. I like that there is a meaning in this animation, there is a complex composition (sound, mimics and so on). Keep working ;)
