Here is some of my sketchbook work. I was inspired as you can see by skulls and artist that use skulls in a lot of their work. I was looking through the book of Skulls, this includes tattoo designs and landscape designs. Its very different and I really like it.
I used acrylic paint and water colours. I also used water pencils which were really effective. Once the paint had dried I used a number a different fine liners all of different thickness to add detail.
