The Hall of Reptiles and Amphibians has always intrigued me. It's dark and quiet and the temperature usually feels slightly cooler (I think I remember hearing that this is intentional, for better maintenance of more delicate specimens). This mysterious ambience is especially palpable after hours.
The magnificent iguana I sat down to draw posed new challenges. It's a beautiful creature, with scales and stripes layered over muscle. At first I struggled trying to capture everything at once. Then I got some great advice (as usual) from Pat to define general mass first using base colors and shading, then to layer on details and texture second. Et voila.
