Are you looking specifically for that effect in Photoshop?
To me it looks unnatural and not like a photograph at all.
Of course, (art and) photo manipulation, like a lot of things in life, is a personal thing and oftentimes highly subjective.
I do like your photos in and around Greater London, as I used to live in Ealing for many years, and I spent a great amount of time in the West End during my halcyon days. :-)
Today, I do minimal work in Canon DPP and Lightroom/PS and follow the rule… Less is more.
Oh… I should confess, I am not a big fan of HDR images… There, I said it.
