it would be nice if the platform had a section of reviews for users, where any user could share their impressions of working on the platform.
I think you can do this section yourself. There simply will be published all the pros and cons of the project.
Yes, there is an opportunity to do it yourself. But its best when its officially from the development team.
"...The ArtPro Marketplace uses a rating system to encourage transparency, set buyer and seller standards and drive confidence."
I think that the reviews will be placed in the rating section.
the rating system is a good way to motivate participants. I think that ArtPro will be able to create a quality market of paintings, using such tools.
