Here's my opinion with this modpack:
(i didn't put the score numbers on each category, just the overall, sorry for the inconvenience)
This is a very good modpack indeed. the wooden wall isn't just another cut & paste palisade wall, it's new, and the eyecandies inside the castle is neat. It fits well in the game, downpart is the size of the castle, it looks too narrow.
I didn't find any bugs in this modpack, the flag when garrisoned is right. Too bad this modpack doesn't really fit to the Spanish. Another little 'unchangeable' problem is the resources needed to build the castle. A wooden castle that needs stone...
This is also a new idea, we have seen castles replaced, but never with a wooden one. The maker sure puts a lot of effort into this, with respect to the Celtic civilization;)
This modpack is good, but doesn't gained the title 5.0. This is a 1 building mod, a very simple mod indeed, with no glitches on it, except some unchangeable problems. I do recommend that you download this. Though maybe you are bored with castle modpacks, it is certainly not the maker's fault.
