The design is very nice and you have many options. It would be nice to allow template color change' like change themes, i.e. instead of orange\brown allow blue\brown. Most companies of several colors in their branding which do not align with the color option you offer. It would be great if you explain how to modify texts and other objects. Sometime it is not so obvious even for experience PowerPoint users. This is especially true for build effects.
