I like it. River Centre I, although much shorter, turned out pretty good.
Shangri La is just a small residential building, not much is to be expected from it. Of course Saskatoon can do better, that's why they have proposals like River Landing and Saskatoon City Centre, both with towers over 90 meters, and nice designs indicative of a much larger city, though City Centre hasn't released its renders yet.
This is River Landing, though I think most people have seen it already.
This is another proposal in Saskatoon currently known as 275 2nd Avenue.
