I have a painting style that suits doing armies, rather than individual models etc and lots of the contributors here are waaayyyy better painters than I will ever be.
I posted once (slightly tongue in cheek) along the lines that “thinning paints, blending, a wet pallet, edge highlight, layer coats, nmm and OSL were all techniques I didn’t use” but it is basically true!
Pretty much everything is black undercoat, drybrushed a couple of shades of brown, base/contrast, touch of wash, drybrush/highlight.
KoW gave me a kick to do unit basing, so the army(s) are consistent, and the basing makes stuff work and is usually what makes me decide on an army!
Kitbashing is a go to, as is trying to make sure the models are built clean and mold line free etc.
While I do tournaments, I’m a casual gamer at heart - go for the atmosphere and meeting people and playing games - so armies get build on the basis of what I like, have an interesting idea for or find an impulse buy. Armies get to about 3-4k then I think about lists!
