Retro Shooter game impression sketch

In the first Semester I had a lesson called "Thinking of Art", in this lesson it was the goal to make a illustration of a game bounded by rules and a target group. My task was to create a illustration that would portray a game set within those goals. And a certain artstyle, the style that I got to work with was Geometric shapes. The game was based upon the shooter games like Ikaruga, Raiden, DoDonPachi and Space Invaders.

Some vehicle sketch

Last week I made this sketch while watching TV, so I just sketched without thinking what the end result would be.

Sketching a Wha.... uhm Submarine

Just a quick sketch I've made this evening.

At the end I didn't wanted just a grayscale sketch, So I decided to tone it a bit to give it some extra touch.
