The problem with this is the opacity of the paint. The Acrylic Vermilion has some very weird properties, it thins down with water but doesn't actually become more transparent. Unfortunately those areas where it's applied thickest also behave oddly in that when you try to manipulate the paint it actually peels off like some fluidic skin, leaving the lighter coated areas tinted [as intended] but those areas that require more colour strip back to the black almost. Of course my impatience got the better of me and I just kept on at it until I'd put too much paint on. I mean it's not bad, but it's not right either. It's too red, too opaque, less like a red head lamp and more like someone's daubed the bonnet with Hammer Horror fake blood!
But overall it's definitely within the same palette as this picture, so if I can fix the OSL I'll be happy.
I'll take a break from finishing him off, do the rest of the bikers and hopefully refine the OSL process so I'm happy.
