Well first of all sorry for the expressionless sillouette, but it seems the forums don't want me uploading an avatar (I get error code -200 )
Anyway I came, I saw, I bought, I played. Now I shall share my two cents.
First of all I have to say that in spite of the game lacking some finish polish and etc, this is a job very well done. Elemental has a very different feel from most formulaic 4x games, however it needs some finishing touches and adjustments here and there.
Well, commonplace errors such as memory leaks apart, i think what the game lacks most importantly at the moment is content (different quests, resources, special sites, buildings, everything) , and it can easily capitalize on the community to satsfy such needs. We already have a powerful tile editor and effects creator, the mod interface just needs to be made more friendly (maybe it already is enough, I haven't looked at the matter in depth, maybe I'm raining at the wet), and if possible more modular so assembling my little fantasy universe wouldn't take a throughtly and manual re-compilation of building databases from three other mods.
Two key points which I'd enjoy seeing implemented are a building tileset framework and a on-the-fly tile editor. A building tileset would allow the binding of substitutes for most buildings (wonders included) on a faction-based structure, so for instance two different kingdoms could have far different buildings and architecture styles. This would add for a greater diversity than just the empires/kingdoms dichotomy we have at the moment. Such tileset would be organized within the faction editor.
The on-the-fly building editor would be an essentially cosmetic implementation but I beleive a lot of people here would like it. With some quick clicks one would be able to substitute an individual controlled tile (eg, a city tile, a resource tile or whatever is under your direct contol in-game) by an already created version, or open the tile editor while in the main game to customize the building. This would help storyteller players like myself, so for instance I have this city here which is guarded by dozens of magical creatures. I could customize its fortress to cosmetically have some effect emmiters and crystals or whatever so supposedly it'd have some sort of magical relay or whateverrelaying the magical energies to keep those creatures. Or perhaps you have this shard here which was the cause of a bloody war, why not add a memorial to its shrine? All aesthetical but still fun. 
Such buildings could be automatically shared via the mod network for players to exchange.
This of course also lays the framework for the more content idea. By unleashing players's creative hability with the tile editor it'd be just a matter of fleshing out all those custom-made tiles into full-fledged features.
