I used acrylic gouache to revise a Doanzaku I created a while ago and made a homemade diorama.
I used dark brown + black + red and ochre + black acrylic gouache, filtering and washing.
My wife has always told me that the Doanzaku is too beautiful, but after discovering acrylic gouache I was finally able to do just that.
I'm relieved that I've finally been able to make a dust cloud-type diorama. The background is free material.
Acrylic gouache has great potential. It's odorless, easy to clean up, and best of all, it's incredibly fast to work with!
