Okay this one may seem a little odd but I've noticed lots of realistic, human heart images popping up around me and I wanted to try my hand at drawing one. I had a student recently use a human heart as the subject of her printmaking and I liked the way it turned out.
Like anything new, this one took some research and study. I even looked over Leonardo da Vinci's notebook drawings of hearts that he created for some inspiration.
Who knows - someone else may think this is cool, too. This one is ready for a frame.
