Quoting Vallkirimrl _
Try to make the front flow better, not so boxy
Put a canard in or move the wings up and add tail fins
try to build upwards, it seems very flat
The Starlifter is not ment for high speed travles but for ultra heavy transportation so it will need a gunship support, Fighter Support, or both. I am but the first thing that need to the top to be done with is the intake vents for the engines.
