First Maze, First Person

I created a bit of our first maze. I think there has to be more space between the walls (would love to read opinions on this). 

Regarding the player, it is first person and for now it cannot move, just look around with the mouse  (this functionality won't be available on our final game). The purpose of this prototype is just to build the maze, not the player, but I think it is important to be able to move through the maze to understand what has to be changed.

Please give me your opinion, @team :)
