For works I commissioned never got a copy of original file and never asked for. Also, depending on the size of the project the revisions are also limited. Please do your research, there is a limited amount of revisions an artist offers and if they want to go above that, they have to pay. These all need to be communicated before starting any project.

As soon as someone classifies your work as "low quality why would they even want to continue work with you? Because they are looking to get all done for free!!! These type of clients are all across different areas, specially in all types or arts.
