Hmm, I must admit, this could use a bit more work (no offense). Firstly, dead bodies are done in the TECH TREE, not the tileset and no body is going to want to modify that (pain in the ass to change back). Same thing for resources like gold and stone. So what do you plan to do with those models? Statues should be fun though! We can have a nativity scene and a santa, and so on...
Trees should be done with modified evergreen trees instead, or at least make the lights look more realistic. Also, a 'glow' effect to the lights will go a long way. You can make the candy cane's the small stones. Perhaps you can think of other ways to fit the stuff in well.
