with my very limited experiences i did change with acrylic paint

using watet to wash off and then cover upith new colour. but i think acrylic should show its own characte, instead of try to challenge the richness of delication. they are different textures. it just like men and women are different. anything going against nature is a kind of aahaaa sorry to say the word: stupidness--- not intend to be offensive. thanks.
