I am indebted to the artists, museums, and scientists who have made it possible to use their models for reference for purchase or creative commons attribution.
I am currently working on updating these references with links. These models are invaluable for understanding the 3d structures and environments for my illustration.

The 3d software I use daily is Modo. I also use Sketchup, Blender, and 3dcoat. The 2d software I use include Clip Studio Paint, Photoshop, Procreate, and InDesign.

Thank you!
