From looking at the models, which I agree are a very good tabletop standard, I would say highlights in general.Any ideas to help me take the standard further?
You've got the base and the wash down. Now you need to tone it up with lighter colors and make it stand out and more vibrant. The highlight process nearly always start after the wash has dried where you use the shadows as a guideline as to where to paint your highlights.
If you need a example of highlights and the process, I invite you to take a look at the painting guide in my signature as that explains the process of how to do it in a 3-step method: Base, highlight and light highlight.
I hope it helps!
