I think this ident is very effective. I liked the rays of light coming out of the world and I think that the music is very powerful, especially with the visual. However I don't like the font of the text. I think that it seems a bit dated now and could do with being changed. I think that the text rolling round with the world is a very nice touch and I might do something similar in my own ident.
Disney ident:
I also think this is a very effective ident. I like how glamorous and powerful the fireworks make it. I also like how you feel like you are moving with the camera as it goes backwards. I don't think that the night background works very well though. For my ident I want it to seem more down to earth and less striking.
