Btw, nice to meet another Dutchman on DA I read you also went to the exhibition in GoT Amsterdam? I might have seen you though 15 minutes inside compared to the huge amount of people in line make it un likely XD Have a great one!
It is a lot of work indeed XD Especially since I am in my highschool finals atm :S. I use Blender a freeware 3D program to do it all. So creatig the 3d models,adding materials, animating and rendering. I am gonna add one more watchtower to the scene and than get the animation rendered. Cheers!
