I have been obsessed with these watercolor crayons for the past few weeks. I experimented with some black scrap paper to create this fancy fish painting. I also used some white gouache to brighten the highlights. 

Tips:

• Build up the colors by layering the crayon colors and then using a lightly damp brush to blend them. 
• Use a stiffer brush than you would use for watercolor. I used some of my acrylic paintbrushes. 
• Don't try to apply crayons to really wet paper because it won't stick.
• I used tube gouache to paint in areas I wanted to be more opaque. Like the body and the white highlights. 

Have fun!
