I didn't know this thread existed. I usually post my drawings in the Canada section. I don't use Photoshop to draw them (I am embarrassed to say I don't know how to use it.) I draw in MS Paint and then do some last bits of shading and blurring in Photoshop. (The only tools I know how to use.)
Here is my latest super future skyline of Toronto. I have a huge high-resolution version as well and also I did a version of this skyline circa the year 2000. They can be found at the Urban Toronto link at the very bottom of this post if you are interested.
First the render of 2015 Toronto. All these projects are either under construction or about to start.
Next the legend to show the added buildings:
And finally the Present-day. (I adjusted the original on which I added my drawings. I cropped it and removed a tall transmission tower that was obstructing the middle of the view.)
