I have come to the conclusion that there are 2 main types of children magic shows. Some are fast paced, and have many tricks. And some, like yours, use only a few tricks. Both are entertaining, but the one using fewer tricks, lets you connect with the audience. And the one using many tricks, gives the guyer more for their money, more magic. Both are good, and I agree, 3 minutes is very short per trick...
I have to disagree with your coment about giving the buyer more for their money, (more tricks). It's the performance they are paying for not to get as many magic tricks as you can into the show.
I don't think Paddy was criticizing him just stating a point. Ten tricks is a heck of a lot for one show. But it sounds as if Wolf did well and it was his first show & he did his homework. Each one will get better AND easier.
If you want to learn to do it right the first time you should listen to people being nick-picky. It was sound advise, take it or leave it.
