The abstract and minimalist style is cool and refinated, however, if the pieces were more figurative, lets say,like warriors and creatures, now that would be epic. They dont have to be super realistic or Magic the Gathering-ish. Consider something like the 3d pieces from Cyvasse. If you are interested I would be honored to lend a hand.
I was amazed, in a good way, for how basic the mechanics are and how they could still lead to complex strategies. I wonder if you are planing to make a physical version of this game. I am sure it would be something both kids and chess enthusiasts would enjoy.As a game, it is solid, as a videogame, I agree that the learning curve and AI is kind of tough.
