I didn't make these refs but I wanted to share them :'D
I really need to organize my art board on Pinterest
my art board for more art refs :D

The first one is a ref for feet/shoe design or placement/angles.
The second one is good for anyone wanting to make a stylized eye and it also helps with expression (through the eyes)
the third one is a reference for how to draw things or people in motion and shows how the lines would look at different speeds.
The last one is just a reference for shoe names- this type of reference comes in handle if you're looking for a specific style or era of shoe for your OC or persona :D
