These pieces are in acrylic and watercolor. I am a self taught artist, so I paint how I want to. I paint quickly and in one sitting, especially I did with these pieces. Many artists work in phases on a piece. The only time I do that is on a floral I have sketched a bit first and then I might spread my time out filling the sketch in with color. These pieces I’m sure break all of the skilled watercolorist handbook, but I have not read it, so I am ok with how these turned out. The top piece is 10x30 if I remember correctly. The next two watercolors are 24x36 and the last watercolor is a 16x20.
