I just use plain flat yellow ... but I think that one a little more pale would work better. I sometimes have a hard time getting a little crazy with the yellow.
Drybrushing ... here's the rub. DBing is a technique of highlighting in which you take a regular size brush and "lube" it up with paint. Then take the brush and "paint" a paper-towel until almost nothing is left on the brush, then gently brush the figure/ part's high-points ... leaving a little bit of the paint. Don't worry about if you don't see it at first. From my experience, the first time that you THINK you see the highlight, STOP! Once you get to the point where you KNOW you see it, its almost too far.
Check out my Think180 SEAL ... I think that I went a little too far on the DBing on the backside ... just to give you an example of "how not to".
