Step 7: Painting!
1. Base coats can be useful: If your mini is going to be mostly lighter coloured, I strongly suggest to do a base coat of white, especially if you sculpted it mostly out of grey sculpey. This will allow you to put less coats of paint and make forgotten areas look more acceptable. If your mini is mostly darker colours, you can paint it black for the same effect.
2. I usually start by painting the base black. This isn't necessary if you want to make a more elaborate base, but it helps me figure out the edges of the sculpture and the base while painting. By the end there are all kinds of colours splashed on the base which are then easy to cover up with a final coat of black.
3. if you notice holes in your sculpture due to bubbles bursting during baking or something (this rarely happens, but I've seen it before), you can fill the hole with the paint. Since it dries up leaving a rubber film, it'll often even out imperfections if you put globs of paint on them.
4. Many details you sculpted can be made clearer and more obvious by using paint properly. In the mini I was making in the pictures, I felt that the loincloth wasn't obvious enough and could lead to confusion. Lining it with a red border made it much more obvious and delimited it nicely. Similarly, adding silver buttons to the many pouches on the mini makes them stick out.
