$10 or under. some of the other sets in the marketplace like alter settings, castle props etc go for that range. the texture on the ground looks streched and not right. the bricks look wrong. a nice old stone look would be very cool. I agree with the others, needs a room at the top, portals looking out or something. Think LOTR 2 towers, where we see the old wizard pacing around at the top of his tower. Or wizards shooting fireballs down at the orcs trying to get in to steal wizards chest etc. it's a different take on the old tower model, and I certainly think you have something there. You may want to create something similar but different and then sell that, so you don't have to wait for the game to arrive. those are my thoughts anyway, keep modeling, you've got a unique style there.
