Artists cost money this is currently a free to play game the second it gets an artist it won't be... best to wait till everything is created and go back for the artistic version this way people can get a feel for the game then if a majority wants there can be a buy able version later with better art maybe, but it makes no sense to waste money on a leech that won't help this early in the games creation
Just food for thought...
I personally see a buch of art people going slower than the game I mean yeah art takes time but makes no sense to get one this early only to have to remake the game putting it out of order with no update for a time.
