Thank you for the kind comments, slowtiger. I have to clear something, I only made the 2d animation of the videoclip 2d characters, the composition was made by guy I only saw once, when I gave him a DVD with the render with alpha of each character's scene. This was almost a year ago.
I never had seen the final composition until yesterday. But that is my own fault. When I joined the project it was all running, characters where cut in parts in psd files, backgrounds, animatic, song, etc. were already designed.
I agree with you in many aspects, but actually I'm very happy with the final composition. It can have some overall designing faults, but I feel it was made carefully, which is not too much common here in Chile, more in very low budget projects like this, you can check some other videos of the same project in order to understand what I say.
One of the biggest problems animating this clip was the size and complexity of the rigs. My computer is very slow and I created rigs with several bones to keep joints clean. I practically had to animate it in blindness, only seeing the construction curves, it was impossible to move anything in other way. Each couple minutes I had to render a preview to see what was going on. I really felt like in 1992. This velocity plus the constant corrections and changes made this project very like a nightmare. This was one of the reasons I never took the time to go watch the final composition before.
This videos are made in full HD. I hope to post that version once the project be showed on TV.
PD: Here is the anme file of one character, if someone wants to take a look
