I have finally come to terms with the fact my shading skills are pretty... (Non-existent) so I'd like to ask advice on how to shade skins. My problem is when I shade it always turns out messy looking since I usually shade a lot of areas in different ways. I'm talking about general advice here so I'm not really looking for specific patterns I can use to shade, just tips.
