Notification Dropdown

As you can see...a notification dropdown menu. It's for an iPad app that I'm currently creating for a client.

Few things I'm unsure of. The navi icon for the notifications. Might switch the envelope to something different. Also not sure how I feel about the square photos versus the rounded edges. I think I might also change the name of the photos to lowercase instead of caps (although the photos will have caps for their title).

Everything else seems to be good to go. Thoughts?
