My personal opinion is that it looks MUCH better than the FW one. I do not have the original FW fortress, only have closeup pics of it, but I have the wizards tower at home and I would trade it immediately for another wizard tower with stone texture like this...
I have the FW one at home and i would say the tower and walls are really really inspired by the FW one. But it's ok, they are great. Some few additions, or modification. emplacement of the door, etc. I think the crenels are really the same. The size is the same too. The work on the stones. The global aspect is really very prooch (not to say the same).
So i would say it's a very nice job for those two components and i would buy them eyes closed if i did not had mines already.
BUT
The gate is ugly


What are those big fatty flat towers on each side ? Come one, guys, you can do far better than just picking the same file than the one of the little towers and had one third of it width and one more window.
It looks really... Boring. Too straight. Too big. Too massive. Too flat. More like a Napoleonian era construction.
The FW one may look too "medievalish" but at least it looks fun and nice.

I love the well ! Very very nice idea.
