First negative painting

I've been interested in negative painting. But I didn't know exactly how it works.

So I looked into website and found free lesson for negative painting.
But only painted by water color. I could try oil paint too. Then I DID!

Not only blue and green

I've been trying to paint landscape using not only blue and green like I always use.

Then finished "purplish" landscape today. I think this is not good enough but something a little different, anyway.
