Animation is hard

English:

Well, I thought making animations is easy, but it's not, I'm still experimenting, corruptions when changing, rotations or positions, does anyone have any suggestions, to make it easier?

Spanish:

Bueno, pense que hacer animaciones era facil, pero sigo experimentando corrupciones cuando cambio posiciones o rotaciones, alguno tiene alguna sugerencia, para hacerlo mas facil?
