Base colouring continued

I put some base paint to the clothes of warmachines' crew members. The Grudge Thrower crew got green shirts and the Bolt Thrower crew red. At the moment they look quite dull and I was wondering, if I should try to paint some patterns to the clothes. Only problem is that I don't know how it looks when I add the highlighting with drybrush. How to highlight so that the patterns are also highlighted ?!? Maybe it's too hard for me, but you'll never know if you don't try :)
