I so shouldn't even have to say this.

If you're commissioning something from me, and you give me a reference sheet that doesn't look like what you want, whatever I make is not going to look like what you want either. I cannot magically read your mind and know that the character actually has pawpads when the ref sheet doesn't show them, or that the character hasn't got headfluff when the reference sheet shows it does.

And to be completely honest, even if you verbally mention that there are some differences, when I'm working I'm looking at the reference sheet. It's awfully easy to forget what you've said and make what I'm seeing instead. I'm WAY more of a visual person than a verbal person. So please get an accurate ref sheet done if you're going to commission something!
