Unlike Migs or Darthrider some people probably are losing a place with a lot of history and value to them. So I'm not surprised someone's upset when their hangout is being knocked over.
That said, I have no relationship to the plains, and feel this is a good prospect for downtown. I'm a little suspect of claims that this will change Regina forever or this is the be all-end all project. It will be a good project for downtown. I think the height of the tower is fine, it certainly doesn't need to be any taller. I would like to see the tower perhaps placed on a pedistal of the 4-5 story base and situated to the centre or NE so there is some seperation between towers on the that east side. Overall I like the concept, the style of the building is quite modern (new) and so that's pleasing and I hope it appears soon.
One little concern in the rendering, the perspective makes that intersection look much larger than it is. I'm not sure in reality how a large tower will look from the intersection, especially with the buildings around it. I'm not saying it will be bad, I just can't see it clearly in my imagination. Also the view is from somewhere in the vitarra building and they seem to have replaced that building with a tree and grass. It will be nice to see more finished renderings in the future.
