You could make your description a little better by telling a little more about your map. How about telling; what heroes are available for play, are there bosses and if so who are they, what items are on the map, etc.
Also, add some BB Codes to make your description more colorful and more attractive to read. Organizing your sentences into paragraphs definitely helps as well. Really, anything to keep your description from looking like a wall of text is good.
Just some tips to get you started on a better description. And remember, a good description always leads to more downloads (unless your map just blows). xD
Now about your map, it looks kind of empty. Actually, it looks a lot empty. You might wanna fill that space with something if you get a chance.
Another thing, if this map's gonna be in a campaign
that you plan to upload to the Hive, than you probably shouldn't have uploaded it here, but instead made a new thread in the
Map Development Forum and attached the map there.
