Hey, I've whipped up a Duskwood to Elwynn-ish sort of model edit.
I've released the edit once already, but that was ages ago, probably last year.
So now I've dug up the files and changed more of it, perfecting it.

What this contains:
Changed skybox
Nearly all creatures switched
WMO swaps
Sounds swaps
Area name changes
And many more minor changes.
I do hope you enjoy using this as much as I enjoyed making this!
