Hello! I do not agree :) you just love watercolors, so for you it seems a complicated technique with oil. For those who paint oil paintings, they will say: "watercolor paints are the most complex." it seems to me that oil paints are a bit like acrylics on technology. but watercolor does not look like one from another of the artistic materials :) Well, it's just my opinion :)

@yakubenko you're right. I also think so!

I wouldn't say one of them is more difficult than another.. I find them both challenging but in a different way!
