Ok after I criticized several others, it's time to back up my talk

Here is a the current status of the map I intend to submit. It is rather likely that I will severely change a few parts, but for now I'm confident that my submission will be based on this version.
I have worked on the gameplay aspects first and not bothered much about aesthetic aspects. I will worry about those later.
The key "new and innovative " aspects which I tried to implement on this map are the following:
-Axial symmetry. Currently all maps in the competitive pool feature rotational symmetry (except for EI), so there are some creepspots which dont "belong" to either player.
-Random building: There are 2 merc camps (lordearon summer), 2 laboratories and 1 shop on the map. And then, there is one random building, which can be either of the following: A market place, a black dragon roost (not on any current map), a second shop, a third mercenary camp (but cityscape variation), or it can be no building at all.
-A contested island expansion (thinking about removing it).
-No items of lvl 4+5, but red camps drop a lvl 6 permanent item (which iirc is only seen on TM out of all current standard maps). This is also so that there will be no auras available at the marketplace.
One final question: Now I've submitted a preview; but I could still change my mind and submit a completely different map, right? Of course then I would also have to submit another preview.
