Here's a tower converted from Spellforge. I made the splash using the building, but tweaked it quite a bit.
This tower will be a wonder in WH mod 2.5, and will spawn a Keeper of Secrets.

Although some parts (like the blue stone) look pixelated and not 3d at all. How exactly did you make it? [/monocle on]
Or was it like this in Spellforge?
