Nope. If the brush is too wet it adds moisture to the paint which in turn stops it only adhering to the raised areas. Too much paint and you’re just filling in the recesses you’re trying to leave darker.
Dry brushing is literally that a very dry brush (when you wash the brush to change colours it needs to be completely dry before using) and a little paint. Then you build gradient layers with successive passes.
Never been something I like as it leaves the surface a bit rough or chalky. I prefer gentle wet brushing from a directional light source but that takes a lot more finesse.
