Timesheets Approval

Here's a screen I've been working on where I'm trying to make approving timesheet cards more interesting. In the current example its showing the timesheet's of a specific project filtered by each user that has collaborated.

The current view shows what a project manager would see and so its highly geared towards approving the work that has been completed as compared to submitting a new timesheet. Timesheet cards can be be approved in bulk or one at a time. A rejection would send it back to the collaborator with reasoning.

Would love to know what you all think!
