I posted the poka dot dapper chap in the 40k Harlequins group a while ago, with a challenge that no one took up. As I've nearly done my Harlequins army, and having several of the old metal Warlocks and Death Jesters doing nothing, plus still having 2 weeks till I start my next month's worth of painting, I decided to have a crack at the dapper poka dotted chap with one of the spares.
Started off with an ushabati bone base coat, then a nuln oil wash . Once dry I gave it 2 coats of Deepkin Flesh, before a light coat of white. I then killed a fine point brush doing loads of poka dots.
