Thanks Roon, Deaf and Lockswin.
She only the second mini I've tried a different approach to black on, I used to just paint a dark grey then wash with black but was never quite pleased with the results. On this lady I mixed a generic black with vallejo medium olive, quite dark, washed with bedab black (heavily) than highlighted with the original colour. Nothing fancy, certainly room for more layers if I could be bothered.
I wanted a suggestion of green so she'd match her ecumenical partner. Who I'll post later today.
Thanks again for the comments.
