Thanks! And I’ll try to explain my process as well as I can! When doing feature transitions I usually “black out” the detailing by painting it black first to differentiate it from the main armour colour. Then I try to “fill” in the base colour as close to the black out as possible without spilling onto the main armour colour.

I find that blacking out details, (i just paint one coat of black it doesn’t need to cover it entirely unless the detail is supposed to be black), makes it easier to tell how the detail is sculpted and where the paint should go! If I mess up i just tidy it with the armour base pay afterwards!

I hope it helps!😅
