Here is the texture breakdown we looked at together in class. Good luck choosing your textures, and though I didn't mention it in class, here are a few recommendations for the assignment:
1- Choose something with a medium-rough texture. Highly reflective surfaces are more challenging and require a more refined skillset than I'm necessarily targeting with this assignment.
2- A few textures to avoid would be: bark, water, and chrome. You certainly can do these if you would like, but they present challenges that you might want to tackle after having done something a little more straightforward first.
3- Remember, you're choosing one texture, and then showing it close up and a little further back.
Good luck!
