I used acrylic gouache to revamp the Doanzaku I made a while ago and made a homemade diorama.
I used dark brown + black + red and ochre + black acrylic gouache, filtering and washing it.
My wife has always told me that "Doanzaku looks too pretty with this paint job," but I finally managed to do that after discovering acrylic gouache.
I'm relieved that I've finally been able to make a dust-based diorama. The background is free material, and the effects were added later.
Acrylic gouache has great potential. It's odorless, easy to clean up, and best of all, it's incredibly fast to work with!
