Why smartphones? It makes no sense, just make it browser based and it will be used by various devices (my MMOs were designed for desktop yet I see a very significant number of players from various mobile phones, even for games where I have zero support of these, nowadays - with huge smatphones screens - it's almost no difference to the user it seems). Two things to remember: include some mode to disable pictures (I dunno why but the players frequently asked me to do it :)) and do not rely on tooltips only (you can't see these on mobiles).
I can't resist this opportunity to dump links to some of my MMOs :) Feel free to examine them (note some of these are online for 9 years now, so they do have some survival traits you might want to copy). Especially observe how the social/group behaviour was mixed with the traditional gameplay without giving the feel of a "Farmville".

What worries me is lack of any sort of "social" components in your posts (what players do with/to other players). If you are going to make the game just as if you were making a singleplayer/multiplayer PC game you will fail... MMOs are a completely different beasts, yes they share some things, but a single/multi strategy and MMO strategy is soo different it's almost a different genre.
Also you need to answer yourself the question if the game is going to be everlasting (incredibly hard to make a strategy game that way, better for RPGs) or will have rounds/eras/ages (periodic wipeaut - it allows very nice mechanics to be introduced and overall strategy is much more meaningful then).
