So, a client hires you because they love your work. The last thing they need, is for you to compromise your best work (your art), because of their feedback.
Fear leads to compromised work
Fear of upsetting the client, leads many people to end up producing work, which looks like something the client could have done themselves. Even though the client’s feedback is offered largely from a position of ignorance (that’s why they hired the expert), it’s allowed to ruin the work.
It’s a lose-lose situation: The client ends up with a poor quality piece of work and the provider has just produced what they know is low quality work.
It damages your reputation.
It’s also totally avoidable.
Listen to (and encourage) your client’s input. But don’t allow it to compromise your work.
