Very nice work. What camera are you shooting with? I love Canada. I work there a few times a year. I was just in Vancouver and there are some recent additions to my gallery of some of the night shots I did there.
Urban Exploration in the photographical aspect is anything that is abandoned/derelict/etc.
I don't want to sound offensive and while this is indeed a very impressive photo but it is not urbex themed. It is a cityscape, the fact that you took it from for example the roof of an abandoned building doesn't change that.
You see my line of thought I hope, this way nearly any urban themed photo could be labelled as urbex.
I understand your point and agree that the photo is a cityscape but it does not change the fact that it was taken while urban exploring (by definition). I think you may need to familiarize yourself with the definition of "urban exploring" because it includes far more than just abandoned and/or decaying structures. Because what you are saying is that rooftopping, draining, climbing bridges or anything similar is not UE. Or at least the photos taken during that activity are not. Similarly by your definition I could go and take a picture of a decaying wall of an active building in a shady neighbourhood and call it an urbex photo. My point is that the definition of urbex is not restricted to abandoned or derelict buildings.
Now with that said, I too prefer abandoned and ideally decayed locations more than anything else but I also like to change things up every once in a while and explore something different.
"Because what you are saying is that rooftopping, draining, climbing bridges or anything similar is not UE. Or at least the photos taken during that activity are not."
I only think the second part, but after a quick ask-around with my teammates and urbexer friends I realized that they were divided on the question much like us now. Basically it boils down to personal opinion in the end, I understand your reasons, but think otherwise, while you understand mine, but have the opinion of urbex covering a wider scale of themes.
