Having fun with these. I never paint this small. Just got a 1/2" cats tongue brush which I really like. It's all I used here. It has a really good fine point that could used as a rigger also. C&C welcome.
John, beautiful work! Reminds me of the landscapes I see in the northern Norway when I'm on my pleinair trips there. You have a correct way to approach a landscape! Love it! I have cat tongue brushes, too and like them a lot.
