Ahh, this club needs more view and submissions. This is what drawing/painting artists need to see and understand things as they are, the next best thing to real life. Unfortunately, we don't all have animals or people around us (or the right environment for that matter) willing to be an example so this is a very welcome source for study material indeed.
Don't worry, I won't use any of these to create a painting with, just as personal studying material.
