Good map, all the basics look good to me. The creep are also are very interesting and different from what you see on the standard maps, but there I dont see any problem with them. A few details I would change:
-Various lvl 3 creeps drop lvl 3 items: The blademaster will just kill these creeps in a few seconds and can get several strong itmes easily.
-You have placed various pathing blocking doodads near forests, and in a few places there are some small gaps where small units can pass through, but bigger units (grunts, heroes for example) cant. You also left a surely unintended path behind forests. Here you have some examples:

-The skeleton between main bases and shops are attacking units that walk past them.
-The market places in combination with the highlevel charged items is somewhat controversial and the consequence are hard to predict.
