Hey Doc, indeed graininess is not really a desired side effect. So far Inwas processing dry brushing with undiluted
GW colors. Following advice from Eki and BaM I did edge highlights with diluted paint and the brush side.
Tried yesterday to cover up graininess with some ink and diluted darker color.
Would probably recoment to try basic layering. Although it always depends on what you want to achieve. If you want to get your minis painted as fast as possible to have em ready for the table drybrushing and washing are good techniques to get fast results.
That's probably why GW for example include these techniques in a lot of their paint guides.
Layering might take much longer but you'll get much cleaner and more controlled results.
On top you get a better feeling on how to thin your paints for good flow/coverage, train your brushcontrol a lot and learn how to mix paints for shadows/highlights.
Of course you can still use drybrushing, for example for highlights but I wouldn't recomment to use drybrushing without applying a clean base layer first.
Of course it's all up to you and depends on what you want to achieve but if you want to achieve an overall cleaner look I would recomment to try the following (maybe on a different model so the that unit doesn't look incoherent) :
In this example I would recomment to start dark and just work towards the highlights. Means, choose dark base colors and light em up in several layers. In my opinion it's easier in the beginning to work in one direction instead of starting with middle tone and work it into shadows+highlights.
1. Step: After priming lay down your base colors. Try to achieve an even coverage. For that thin your paints a bit to make em flow better. It might take a couple layers, depending also on the colors. For example yellow will not really cover over black! Try to be neat and work through the whole mini.
2. Step: When you have established all base colors mix a bit lighter tone of either the colors and start your first "highlight" layer. Leave your dark base color in the shadows.
3. Step: Like step two but this time with a lighter mixture. Repeat until happy with the result. -> the more tones you mix and the more layers you paint, the smoother the transition will become.
But most important is to have fun and keep painting
