What are your favorite drawing references?

[phlegmatic]

Drawing references are images of artwork that one artist may use to help figure out how to draw a current piece they are working on. It can provide ways to draw limbs, facial features, geography, landscapes, and any other forms of art.

For different art styles you create, what are your favorite drawing references? Why?

At the rare times I draw, I like using photos I made of landscapes, people or anything. However, for hairstyles, I mostly use the professional photos of hairstyles that you can find online.
