As a graphic designer we need a space so clients can give feedback on images/concepts that we offer.

Edit image with comments (similar feature to project huddle)

Add images to the image (similar to a screenshot tool, like snag it where the user can draw rudimentary shapes, add text, arrows, etc)

A comment box to add further commentary that won't fit on the image so the client and the team member (from my team) can communicate with the client.
