The main thing that bothers me about the spacecraft is something that will probably not bother anybody else. Specifically, while thrusting, the pilot will feel like “down” is the direction the thrust is going, and the nose will be pointed “up”. But since every other spacecraft in movies and TV suffers from this inaccuracy, you can get away with doing it as well.
The axis of thrust of all the rockets has to pass through the spacecraft’s center of gravity. Otherwise the spacecraft will tumble when you turn on the rockets. This means that the main fusion drive should probably be in the center of the aft end of the ship, instead of at the lower aft.
And a line connecting the two external engines has to pass through the ship’s direction of flight. This means they should be on opposites sides of the ship instead of below. Alternatively you could add a third external engine on the “top”, so from front view the three engines formed an equilateral triangle.
I am unsure as to the size of the ship. Is it just slightly larger than a man, or is it a titanic egg with a huge front window? An external door and/or ladder would help establish a scale.
I agree with Orinoco that it could use a radar dish.
You might want to add attitude jet clusters aka “Reaction Control System” or RCS.
and scroll down to “Things get real nasty if the ship is a tumbling pigeon”. In the pod with arms, the RCS can be seen on the right.
Also go to
and scroll down to “How does the pilot aim the ship?”
The ship technically should have a section of hull with ridges to act as a heat radiator, but this can be ignored.
