> Do you have any advice on how to paint a figurine?

One or two "Army Painter" brushes will do you fine.

Thin paints a little as you work, the paints in the bottles are a little thick.

Paint a base coat layer, wash a darker color over that layer, drybrush a lighter highlight over that layer and you'll be 90% of the way there. From that point, it's just practice and adding skills.
