That looks good. A couple of things to think about. The cliff wall is very regular. It almost looks like a city wall instead. Are the round objects columns? If so they might look better with a base of some sort. These kind of maps can almost always benefit from a bit of clutter as well think about the "atmosphere" you are trying to depict. Is the club crowded? (you don't have to use characters to give the feeling of a crowd) Is it a "rowdy" place with loud music and a rough crowd? Is it a more quiet "classy" place where the richer criminal element of your city meet to discuss business? Answering these questions can help you to "see" your map the way you want others to see it and can help you set the "mood" of the scene. Keep us the good work
