I don't know why the .. did you get used to rate somebody's work, he clearly wanted to get comments and/or instructions on how to improve his mapping instead of flaming posts "OMFG FAIL SUX PLS".
So - back to the topic - Amardus: It is indeed undetailed and squary as Epic said, how about looking inside Tibia how caves, and areas similar to the one you have done look like. There are no roads to some buildings in the city, the rest is empty and without trees/bushes etc.
So kids, do you know now what does a good 'comment' look like?
