Very very nice. I can't wait to see how it turns out
Two recommendations:
1. I'd set the water level just a smidge higher. it's only waist deep (uness you intended it that way).
2. Check out the southeast corner of your zone. The water area should extend farther south, to the zone edge (go there ingame and you'll see what I mean).
Otherwise, it looks great so far. I can see, though, that I should see about making some more taxtures to make the land more varied.
By the way, OpenZone 1.9 will support object grouping and ungrouping. I'm putting the finishing touches on it and it might be ready sometime tomorrow.
