Not bad at all for a first shake at a proof of concept, though I expect you would have quite a lot of work in store for yourself if you decide to pursue this. Even a basic 3D model is a lot of work, and throwing transformation into the mix is going to add to your load exponentially with every form you add.
That said, I do love me some dungeon crawlers, and TF in general is badly in need of a good effort at 3D representation. I can't speak for the entire world, but I would definitely pay up for a decent 3D TF game with some solid content. Please keep up the good work!
