Sorry for lateness, due to having this new forum all map submissions are finally in one place, rather than 5 different forums.
So the map is very basic and lacking everything. There is no clear theme. When building a map always plan what theme you are going to do first, try to be creative when picking a theme too, and never restrict yourself to a few blocks. To be more creative, experiment with blocks, see what works, what doesn't. Always try to do more than what you are capable of, that's how people produce great content, by pushing themselves.
