The amount of detail in your work has gone up so much! It amazes me how much you have improved, Not only since May 20'th, but since i first met you too.
The background is impressive, and that's because you used to complain about your backgrounds. The lighting makes it look so realistic.
I can't really see much of the shading, but considering its a nighttime piece its kind of hard to, but what i can see blends very well.
I know critiques are meant for the artist to find the flaws in his work, but i truly don't see anything wrong with this.
The Background could have meshed a tiny bit better with the foreground, but that's all i can really think of.
All in all, Im proud of you man, you really have improved a ton. Im proud to call your work what I strive to achieve.
