This is part of a very unique sculpture in Commerce Place. Commercen Place is a combination Retail and Office Complex located right downtown on Jasper Avenue.
I took the time to take a few shots of these as I was on the way to meet Melody at the bank.
I was only looking at the faces until I read what @summerfield said about fish and a dinosaur. Then I looked closer and saw those details. I also see a deer at the top right. That must have taken ages to create. This is a really cool sculputure.
