I am making my own town spawn too, 18025 or /v +town Anyway i like the spawn we have atm, i have great memories of spawn
Well, if you fall in water easily I guess so but other than that I can always replace with ice or something of that nature.
Maybe change the lapis blocks to packed ice, the ore blocks to lapis blocks, and the surrounding water to ice? If in 1.7, that is. Or keep the lapis blocks and change the ore blocks to packed ice and the water to ice. Though I don't mind the water and think it looks fine now.
Looks really nice, more of a lodge-y, homey feel. I like it! What are you doing with the surrounding podzol? It looks prettyy good with the new ice/spruce area, actually, since podzol and spruce are pretty much spawned together. They look naturally and woodsy that way. Edit: Dark Oak/Spruce are similar, doesn't matter which you use, though the DO looks good now.
Does bring a wild air to it all. Maybe use redstone lamps as permanent lightning to continue with the same feel?
