with respect softus, what is the point of finding fault with that? it's all about enjoying the imagination.... not looking to see if the lighting is wrong?
You call it 'finding fault', whereas I call it observation. I guess different things appeal to different people.
Based on my knowledge of CGI, it's quite a good sequence, but I suspect the subterfuge would grate with any musician's sense of timing, and I can't help but wonder just how much more effort it would have taken to make it more convincing.
