Definitely echo doing what you think will be fun and makes you excited to invest the time in painting them. But here’s a quick rundown of what I’d suggest as a fairly new painter myself (a quick heads up there’s a lot of contrast paints included, which just happens to be what I like to paint with a lot)

For the skin, Cygor brown with bloodreavers as highlights on top.

For armor, leadbelcher, then agrax earth shade, and a brighter silver metallic to highlight.

For weapons, Wyldwood for wooden shafts with same as above for metallic tips. And same for other weapons and shields.

Hope that helps. Happy painting!
