This is good general advice. If your software needs a "tour," that's a good indicator you should work on your UX instead. If you're just excited to tell the user about a new feature, they'll discover it when they need it.

I think in this case a tour is fine and sort of the point. But I disagree with you generally.

Not everyone will come to view this model from the same vantage point. Some will simply be curious about some famous software that they don't happen to use. So the tour is an excellent idea. Great presentation. Congratulations.
