Oh? Then you know of the infamous, Feng Zhu. If you notice in his pictures on his web site, he has a small tutorial. In the tutorial, he has a few picture sequences of a drawing he did. In the middle of the picture sequence, is a picture that is very much like yours, hense the reason I believed you should finish your work of art. I think you did a very good job, but a finished job is far better then a partial work of art.
ah, I see. Yet, I won't really agree upon what you said in the end. I believe that a rough speedpainting can have as much strength and atmosphere (well, sometimes even more) as a finished piece. In a finished piece the overrendering kills some of the initial freshness and intuitive strokes which I like a lot in a painting.
I really love the style of this, gives a futuristic / tech noir kinda style.
All the detail is amazing, especially on the architecture, with all the detailed lines and tiny lights.
The colours are fantastic, everyone seems to be chosen with care and it really pays off.
The people look really dark and mysterious to, cause of their dark colours and basic shapes, which make them seem kinda lifeless.
