I used balance in my artwork by trying to make the amount of black and white equal to make the drawing pop. I tried to fill the background with coral and sea life to make the eye move around the page, but the fish is the focal point.
Texture and contrast were important because there were only two colors you could have on the pictures; the paper and the ink. I didn't want the print to look totally flat and lifeless, so the stripes and dark parts of the fish were kept, and I cut out the rest so the fish would pop out against the background. I also tried to use a variety of thick and thin lines to add some texture.
