Bravo on those temples- they look very well thought out!
I always like when people do quirky, impractical builds. They really add character and depth to a world. Especially when they have a little lore- personally I base my statues, shrines and whatnots to events that have occurred in my world.
Love your building style- keep us informed!
How about, say, a Mesa Temple next, an Ice Temple amongst the spikes... maybe a Mushroom Temple?
I absolutely want to build an Ice Temple off in the tundra, as its the last of the main eight temples I wanted to build. The problem is that the nearest tundra to my spawn is several hundred kilometers away from my spawn. So I may have to make it in another world. As for mesa, I had originally just lumped that into desert. And to be honest, mushroom islands never really appealed to me. Though I suppose I could make some smaller shrines for them.
