Seen many melee maps here that is quite bad but to be honest for you, this one looks decent but still not up for approval but if you are up to improving this, it would be great!
So first, the terrain could still be improved. The variation of the tiles could be better, find something more that could fit. Also, you could still decorate a bit more the creep camps and not only that but the whole terrain because the feeling of emptiness is still there even if you can say that you decorated it with doodads/destructibles a bit. And using a manmade cliff as a platform for dirt tiles looks a bit off if you are to see the edge looks cut off. Use manmade cliffs as a platform if you are to use manmade tiles for it and the other way around, if you are to use natural cliffs as platforms, use natural tiles with it.
Now, for the item drops of the creeps, randomizing them is the first step and you seem to did it perfectly but here comes to your flaws, mostly in melee, drops are only Miscellaneous and Permanent Types but you set up all Types and that means even campaign items will drop so better change them to either Random Permanent Item Types or Random Miscellaneous Item Types. Your Item level drops for creeps are also quite high lower them by one or two level, what I mean is the Item level.
Lastly, your description here needs more information to start with. Do describe the map, like how melees are being described. Through stories that supports your melee map. Then some changelogs. Also change the map name to an English one, map must be in English including its name. It is in the rule that you must create a decent description and that it must be in English language ( even with a little amount of BB Code usage just describe something in it and you are done)
I am saying this because even if you are a new member here you are already breaking some rules. And you are not an exception in the rules and to its punishments upon breaking them.
Hope this tips helped you as a new member. Have fun making maps!
