Well, what makes you so sure you have good taste? You have a taste, and many designs probably appealed to that taste.
I’ve seen first hand bosses of companies favor designs (half way decent stuff) that appealed to their tastes, but there were elements of the company that knew his/her taste was a little bland.
Amateurish is harsh. I would agree that it looks slightly dated, though not in the wrong way. If you go through the brochure, you get a sense that a lot of thought went into the design itself.
