Re: A parade of spaceships...
looks like it needs to be longer.
Well I worked right off (on top of actually) screencaps to get the shape and proportions right. Also in the elevations you're not seeing the curvatures of the shape or any perspective so that can distort how it appears to some degree. Still if eventually necessary it can always be stretched a bit.
