Critique for First Captivate Project

Hi everyone,

As a fellow creative, I recognize the sin in what I'm about to ask. Would anyone be willing to provide a critique, however superficial, on my first eLearning project? I wouldn't be able to pay for it (hence the sin); the project is a photo-based teaching tool for an environmental non-profit. Since I'm entirely self-taught, I'd like to know if I have any glaring file management errors or if I'm using workarounds unnecessarily. This critique could be as in-depth or cursory as you're willing to provide.

Many thanks in advance!
