Part of a personal project I'm working on right now, to experiment with unfamiliar art styles and practice lettering skills by drawing animals. I enjoyed this foray into digital mosaic (or fauxsaic as I've seen it called).
There are many reference photos for iguanas on the internet. This drawing relies on three difference reference images. The drawing was done with a micron .005 pen and then coloring added with pencils. He was a lot of fun....I think there may be more iguanas or other lizards and reptiles in my future!
