A secondary thing for my main ref sheet compiled from getting a whole bunch of art since making it and seeing a lot of the same things missed repeatedly.

I didn't even catch that most people were giving them brown eyebrows until someone gave me a WIP where their eyebrows ran right into the face stripe and realized looking back through, holy crap, so many people did that, but usually it's not so distracting that I catch it or am bothered enough to ask them to fix it.

The leg stripes though, usually anything with an inner thigh view is off at first; it's why I like when they send me an uncolored WIP so I can quickly plot out where everything goes as viewed and send it back to them.
