Folks who want to see for themselves can take advantage of the Jane's Walk in a couple of weeks:

We did a self-guided tour, following this route. Came east over the flyover and down the bike path to Underpass and Mirage, down Eastern to the corner of Cherry to see Site Specific, then down Cherry to the Canary building and back to Corktown Commons. It's a lovely walk.
I really think that people are working really hard to hate on this, quite frankly. The guy that doesn't want to go through the columns to get to the spa or Dark Horse? Well, use the entrance, dude. Or, in the case of the Dark Horse space, use the side door off of what I expect will be a Trump-sized
huuuuuge patio. The entire Front Street extension promenade has been designed for walking, playing with kids (the blue Water Guardians sit over a splash pad), sitting under trees (benches around a little 'courtyard' space that'll be lovely come spring), and still have room for cars in the middle and shops on the side. Once the trees leaf (and they don't even have to grow much, as they're already planted at a decent size!) this will be spectacular.
Now that the rocks have been covered at the back of the Commons and along the bike path / Bayview, there is a ton of green all the way north to the King/Queen triangle. And there's pops of colour everywhere. But, even if you only count buildings, there are five grey brick buildings (big, true, but not overwhelming by any means), three red brick heritage buildings on the Eastern extension, two red brick heritage buildings at Cherry / Front, and in the greater scheme of things the red brick and glass of Distillery just across Cherry, and the black and white of River City on the other side of River square.
Funnily enough, the only part that seemed 'too grey' to us was River Square. The grey gravel and black planters need the flowers planted and trees leafing to liven it up. Still think that was a missed opportunity for a pétanque court...
While I don't know the leader of the walk and whether she'll be interesting to hear speak about the sculptures, I would definitely recommend a walk through WDL. This is an amazing re-build of a part of the city that was a real travesty just 20 years ago.
