The mockup is stunning and so fresh! Not sure though where you got the style from, if you can refer me to some more pieces in similar style that'd be wicked (I really like it).
Anyway GJ as usual Adarias, your tile and sprite work is inspiring to say the least.
But I would love o see some buildings and hills done in this style, just tos ee what you come up with =P My guess is you'd go with something japanese looking right?
