Following situation:
A group of people my brother is friends with are willing to pay for my work. They want an illustration with several of their characters from an MMO to hang on their wall. This is the base of the job.
Now, I'm relatively new to Freelancing and price ranges, and the first time I've worked for someone the piece was highly underpriced. What I DO know now after a simple research is that the more characters are on the piece, the more expensive it gets, naturally.
But what I want to know is how it works with multiple clients who ask for the same job. Even though I will most likely be working on a single piece, should I up the price considering I need to satisfy every one of the clients?
Every word of advice and experience is appreciated.
