Stage 4 - Highlights

I used the new wildrider red and a steady hand to do the hardlining on the armour plates, and auric gold for the legs/arms section. The eyes were done in celestia grey, with pallid flesh points, as was the powersword on the squad leader.

I have the bases to complete for sure, and im debating another targeted highlight on parts of the armour, but dont know what to use to avoid it looking silly, any suggestions guys?
