E-Learning Heroes - Advice and ideas from the Articulate Community

Well, I have pretty much settled on the flow of the course and how it will be presented interms of content and quiz,

The courses will be for AirForce - new to the career field Bio meds.

I want it to appear very professiional and very Airforce like.

Any ideas how I can capture this? Should I use Airplane simages or Airmen Images etc are some of the areas that I am struggling with.

I don't really have any advice about the design of your course, but wanted to share this resource with you. The Air Force (United States) has a large collection of photos that you might want to look at for inspiration.
