This is my first genesis framework theme alteration. I started with Platinum. It is pretty conservative because that is what I was asked for. I did create an extra widgeted area on the home page and forced sidebar-content-sidebar for the homepage. This allows for a featured page widget in the top so that the client could insert a welcome message and the DCG for featured posts and the featured post widget for the latest content. The concepts were also client requested even if the implementation was much better than they expected could be done. DCG FTW.
In general I'm pretty happy with it and learned a lot about the Genesis framework, which I love. Apparently others like it since someone already knocked it off.
