Last night I did more leaf study and did this one. I had some hard time painting those light color leaves on the wet dark background. I need some help on this matter. Does anybody know a very quick dry medium such that I can paint on top of it without picking up paint underneath in a short time (a couple of hours or even shorter)? Have you tried paint acrylic first and paint oil on top? Please let me know if you have some good tips. Thanks.
