The glass atrium is a nice feature which differentiates it enough from the 3 sisters. Seeing these high quality render I am not as concerned about everything looking the same
The atrium could be...
1. Pool
2. Event space for residents (including three sisters residents)
3. Dining/Restaurant (something with this much natural lighting could make a nice brunch spot)
4. High end cafe (epoch)
5. Pickleball court
Keep in mind this will now create a better flow into the riverfront park where things like ribfest and other festivals are hosted. This is going to vastly change the amount of activity on the riverfront which has been mostly dead at that end of downtown. There will be a much safer feeling using the trail system in this area.
