This is a personal piece, aimed to practice drawing a semi-accurate heart. I had lots of fun with it, and ended up stylizing the piece using my own personal technique.
This piece was a massive challenge. I know almost nothing about the human heart or what the arteries look like. I had relied heavily on medical reference images to create the sketch for this piece, so the arteries in this image are actually semi-accurate. Once I got the sketch done, I simply lined the image and colored.
