I went for a "Tron" look for my stealthsuits to imphasize the effects of their armor. The hardest part was getting the highlighting on the dark armor to actually show up. Overall, the green lines came out well though.
Tron. Neat. And effective in this application. I can't see because of the photo, so work on that some more and we'll see more of the beauty of your paint jobs.
I really like the strong green highlight especially for the stealth suit (in fact, you've given me ideas for my Tau).
