First boards

These are my first boards to try and get across my look and feel for that game that I will design:
Board 1
Board 2

Idea

As my design boards are not quite finished yet, so I cant add them onto here, I'm going to try and outline my basic idea.
The game will be set in the year 2020 but as tho it was designed in the 1960's. So it will have that 60's futuristic look to it. For example there cars having like big wings on the back.
It will also be slightly based on the classic Space Invaders game, the way that you will be flying a "ship" around a futuristic city and alien spaceship will be dropping down in front of you, shooting at you. But as well as shooting back and avoiding them, you must also wive your way in and out of the buildings.
The buildings can be shot at and blown up by the aliens, but also by the player, all through the idea is to protect as much as possible of the city.
To get an idea of that the "ships" and the city will look like I will continue my research into what the past thought of the future, mainly what the 1960's view was of the year 2020 as well as even earl yer. For example the film Metropolis was filmed in 1924 and is set in 2000 and shows a very futuristic city landscape.

Game ideas

While reading through the project brief again, I picked up on the part stating "industrial cutesy cubism". From this I have now started producing a number of test environments in 3D around this cubism idea.
One of these ideas is setting the whole idea for the game.
The player will control some sort of "ship" around a futuristic city. The city will be set at night and be made up of huge skyscraper buildings, all look very similar. As its night, the buildings will all be lit up, with the night sky overhead and a dark fog underneath the payer. This fog will be in place so that the ground does not have to be modeled as well as adding to the atmosphere.
Alien ships will fly in front and have to be shot down by the player.
As well as the ship exploding when hit and shot down, all the buildings will be able to take fire from both the player and the enemies.
