Below is what I ended up with but you can see where it evolved from.
I wanted something that would incorporate the graphic pattern of the fingerprint and that would symbolize love and a heart connection.
I was happy with how this came out. I like the clean lines and the kind of organic silhouette of the heart.
I find that doing a bunch of "thumbnails" or small black and white sketches helps me explore thoughts and ideas. They are fun to look back at too.
