I was working on character designs for a client and I was given vague descriptions to work with. Since I wasn’t given a lot of detail I decided to get creative. When I showed it to the client he got mad.
Client: No, no, no, he has to look like THIS!
At which point he pulled out and showed me a previously commissioned piece of the character.
I’d asked for reference several times before this point. I guess he hoped I’d guess right.
