Um, the first photo you posted is of 6 girls in their panties in a place called "Temptations Ladyboy Bar". And believe me, I'm 23 and the last thing I am is offended by this, but please don't call it "street photography.
Jessie! See the sign post? That indicates that this is indeed outside. But if we were to get super technical, you may be right as I am not standing on a street or the subject on a street. However it is practically an extension of a street where lots of bars are.
And yes, I do realize the obvious that 1dx and 85 1.2 will give best results at night photography. However, I never read about this combo for night street photography and so expressed myself. Most talk about Leica or such and 35mm lenses for street photography but not of this combo. This combo works on various levels: 1. Low noise at high ISO. 2. Weather sealing 3. Great out of focus background. 4. One can be a bit far from the subject and get candid shots.
