They can be f***ers when it comes to that can't they!
Hadn't commented on your work although I had been following your progress, I really like it, nice render and modeling!
The first video you posted a link to made me a little dizzy!
It was spinning a little too fast, the second one was spot on, pity about the music thing, if you know any one that can play the piano maybe get them to play something and do it that way.
Excellent work whatever the case!
