this is my submarine i built with my lego blocks.
Step 1: Base Plates
First I started with 4 base plates of any size and stack flat pieces to make it look like waves coming off of the submarine. then i made it look like it was going through a ice field so i built lego ice chunks floating around it.
Step 2: Building Submarine
Then i took gray pieces and built up the shape of the top of a submarine. it was hard finding alot of gray pieces so in the middle of the model i put different shaped basic bricks in it.
