Artist's studio in a brothel

Without being a first-timer, I do very few scenes in set and perspective. Why? Because perspective! It's time consuming, easy to fail, complicated to master and most of the time, people have no idea how much work it is, so it's not even profitable.
But I took the plunge. And if it's not a first, it's still a milestone; I haven't done this kind of thing in years and I've rarely tried so rich (because actually, the perspective isn't that complicated) and me and vanishing lines have a long history of hate.
But above all, there is my way of inking... it's easy enough in clear line, but to find out how to dose the shadows, the black flat tints, etc... well I had never tried so much and... and I'm getting there! Well, it's more than 8 hours in total, but it's a success, for a first attempt with this style, and the time spent on it is not that bad.
A color version is planned! either by the colorists working on my current pro work, or I'll do it myself. And, yeah, I'm really moved by the result. To be tried again! And it's planned!
