This is still a work in progress, PLEASE give me references to add to this, any and all are appreciated!
All artists need a good few references. ALL artists, even extremely good ones use references from time to time.
But sometimes it's hard to find good ones. It's time consuming and sometimes you aren't even able to find what you need.
I'm not saying this will give you everything you need, but it should help out a bit.
I cannot find every good reference so I beg of you: link me the references you used! My only requirements are that there's no nudity or anything that might get either of us banned and they have to be credited if they are not public domain.
Everything will be separated into general categories in separate posts below, then separated further into subcategories in the post.
