I like painting almost as much as playing the games π .
Don't be scared to try it out, just watch some video to learn the basics and then try it out yourself. It's surprisingly easy if you know some of the basic techniques. Prime your minis, use thin layers of paint, look up how to dry brush, and get a wash for shadows. Then you can start adding other techniques as you get better.
Or if you want you could follow along a recipe from a video for your first mini, that way you know how it will look and can learn the colours and techniques yet be sure that the colour palette works.
Worst come worst it is possible to strip the paint, but I doubt it will come to that.
