Here's a new set. Without a doubt, the type of puddle is a key element. Without the perfect conditions it is an obvious attempt and not a real success. When the reflection is so balanced that it is difficult to discern the sky from the water it is a much more satisfying result. I've been in a lot of back alley's lately, and discovering that I don't always have to frame the buildings or other objects inside the image. In the first and third image's the lines all leave the side edges, giving them more of a perspective of looking down, the other three, which are more controlled, have a cleaner look, but less depth.
The top image is from Banff, with Cascade mountain in the centre, second one if from a Costco parking lot in the NW, third near 42nd avenue and Macleod Trail, fourth and fifth in Victoria Park all in Calgary.
