I would do it in acrylic now. It is just more durable. Q Oils just cant hold up in someone's wallet. Well they are sticky. N Mostly I work in oil because it is the easiest to get the results that I am looking for.
Acrylic is much harder to blend colors.
But I work in charcoal and I have done print making, Xerox transfer and etching. I like all kinds of things. I like when there is a sense of history in my work. Tradition in a way. I have been influenced a lot by my grandparents and being an art history major.
