Islanders analog game

Board game project for Game Design course. Outside design itself I was tasked with creating the board, with 3 different terrains that needed to be clearly distinguishable from each other. Each board piece consists of 4 tiles, and 9 pieces make up a random 3x3 game board.
In the group we agreed on simple design so I had some challenge to make an interesting and pleasant design while keeping it as simple as possible.
