These are the 3 classes you can pick from ships. Each one has their own respective upgrades and skills, but are best for different situations. I improved on my previous examples, but critisims are always welcomed.

The first one is based on the the shape of the circle, balanced. The second one is based on the square, supportive and strong. Lastly, the last design is based on the triangle, aggressive and powerful.  

No copy, copy. Its illegal to do such acts of copying.
