One of the last commissions I'm working at nowadays. And of course a few intermediate steps! I wasn't going to save any, but the customer asked to proved him with some updates and I didn't mind to.
I always try my best to make a cooperation comfortable for both me and my customers, and I'm quite sure a lot of artists do the same thing. So if you're curious, don't be shy to ask for an update from an artist you ordered an art from ^^ It often helps to avoid mistakes and to make an art look exactly as you wanted it to!
