I think it's quite good. If someone likes Radio Ga Ga, will enjoy it, I think. But I would change the ending, for me it's too simple, I would add some reverb or something. Technically very good.
It's OK, and some of it is nicely executed, but there are some very noticeable edits, at around 3:05 (although the phasing bit it goes into there is nice), 4:04, and 4:43, which really need to be worked on.
It's another one of those tracks that will appeal to some, but personally, I'd rather have heard more of the song. I also agree with Piotre about the ending, which is rather too abrupt.
