Thank you very much, I know I'm not the world's best painter but I strive to do what I can as well as I can while gradually improving so 'good execution' is what i like to hear . I'm glad the glossyness doesn't detract too much from what I was trying to achieve.
I do own quite a lot of model colour, in fact that's largely what Tuco's painted with (and I think it's clear he's significantly less glossy than the Witchling, at least to my eyes), but mostly greys, reds, browns and purples, so none of the colours I wanted to use on the Witchling. I'm using VMC French Mirage Blue as the base for Sonia Criid's trousers so we'll see how that goes whenever I manage to finish her up. So, far the basecoat looks pretty matte.
I'll give black a try on the next base, if that doesn't grab me then I think I'll stick with brown.
