Tie Fighter - Basic Cockpit Shape

I have begun working on the basic shape for the cockpit of my tie fighter, using a sphere primitive I simply deleted a few edges to make the front look less rounded and extruded both the front and rear. After this I created a cube primitive and made it into the shape I desired, I then aligned it into the position I wanted and duplicated it in order to have 4 of them. Using these 4 shapes I cut into the top of the cockpit using the booleans difference tool to create the shallow grooves in the top.
