This is a good plot, I have a suggestion for making the trees better tho! try using worldedit! just make an Air gbrush (//gbrush air) and then take an item and use it as a brush, like for example a sword. while holding it type the command (//br sphere 10%35:6,10%95:6,80%0 3) that will make some spheres where you right click (with a percentage of 10% pink wool 10%pink glass and 80%air) without damaging the wood.
overall a great plot! gonna see it in game soon! have a great game ^^
