Below is an close up image i found of a lizard. This shows the detailed nature of lizards bodies - the intricate scales, cracks and folds in their skins.
This is a texas horned lizard. I found this image interesting because of the spines that the lizard has round it's neck, which reminded me of a dragon or a serpent.
Above is an image of a gecko, which has an unusal pattern on its body. Most lizards have some sort of markings on their bodies (sometimes to camoflouge them), which is an element to consider when thinking about how to illustrate my mythical creatures.
