Gigantisches außerirdisches Kommandoschiff führt Invasion über blauem Planeten an

A gigantic alien command ship in orbit over a blue planet supervising a full scale invasion. Invasion ships can be seen headed for the planet far below the command ship. The command ship is colossal, sleek and deadly with weapons and sensors all around. There seems to be an off white colored organic exoskeleton type indestructable armor fitted to the massive ship with a smoothly integrated evil looking alien skull into the front of the gigantic dreadnaught. Done in a fantastic detailed science fiction space opera style
