This is awesome work Jawa! Care to give me some feed back on my latest bits?
They look nice, for orks!
Without knowing your process it is tough to give feedback. Black is tough. First it looks like you need to spend more time going over the edges of all of the clothing with lighter greys. Not really light greys, just a few shades lighter than black. Same for your yellow. On mine I do 2 or 3 layers of Yriel yellow, then give it a glaze with Lamenters Yellow, then two or three layers with Flash Gitz. All of that on top of a base layer of Iyanden Darksun washed with Casandora Yellow. It looks like you did green on black? I would start by spraying your orks with Army painter Angels Green and use that as your base for the skin. Hope that helps!
