Go for it.
Hello...I'm completely sold on water mixable oils. Couldn't stand the smell of the chemicals of regular oils, and I find that washing out my brushes with soap and water to be delightful. I like watercolors for that reason as well. The "pop" of an oil compared to an acrylic painting cannot be compared. If you don't like what you put down, you have time to wipe it off. After they've dried completely, I find that using a cold wax medium as a finisher is super. Cobra is best, but you don't have to go into debt to pick up some good student oils. Have fun!
