3D HeroQuest board

Hello all! Here with a project that will (hopefully) be as awesome as I've imagined it. I'm making a 3D version of the base game board, adding walls to the design. I will be utilizing Hirst Art molds for the majority of the project. I am also beefing up the tiles to 1", so as you can see below, with the walls and bigger tiles, this board is going to be massive! 36"x28" (plus a 1/4" border all around).
I tried to do this with pine wood before, but ran into an issue with that, so now I'm back to the cork board. Here is where I currently am with it:
This is how the board will be divided up (gray areas are walls):

Notice the size increase:

Newly cut cork board (Ran out of cork so that will be finished tomorrow):

I'm still waiting on the Hirst molds to come in. Tomorrow I'm finishing cutting out the board and will start gluing the boarder pieces down. I will update when I get all that done. Thanks for looking!
