My first time using gouache paint. While painting this, the first 3 rows was pretty simple. it took a bit of thinking while mixing, thinking if the color is right between and if it would be easy to mix colors for the next row. Hearing others talk about the difficulties of the last row, I took a while to think while mixing just to make sure its just right of the grayscale. I did not want to paint it again if I messed up haha. But painting was pretty fun. I love the matte look of the paint when it dries.
