Some exotic knight dude or dudess from Privateer Press.
The colour scheme was inspired by Hellpoint, a cool sci-fi soulslike game I was playing over Christmas. Yes the armour is kinda fancy, yes it was a paint in the arse to paint, but no those two aspects are not related! The actual armour painting was pretty simple (dark turquoise base, black lining, two translucent purple highlights, one brighter purple highlight, lilac edge all over, pale cream edge on the sharpest points), but repeating that over the whole thing did my tits in, and that would have been the case for any colours.
It's just like all those naff Youtube videos floating around: "INSANE HACK TO PAINT AMAZING SPACE MARINES QUICKLY OMG!!!" which show you how to do a lovely swift kneepad in 10 minutes.....and then all you have to do is to repeat that over 38 other sodding armour plates 🙄. "Draw two circles....now draw the rest of the fucking owl" etc etc.
