Sometimes even when the client likes your illustration its not right for the clients brand.
This is some packaging I illustrated that got killed. I've removed the company and product name that was in the steam cloud because the product is still in development. Too bad, it was still fun to work on and I'm happy with the result. Especially as there were a lot of parameters with the packaging I had to keep in mind for the design. For example, the white space over the creatures face is a cutout that reveals the products great googly eyes.
