Nice. But the image needs a scale range somewhere. Say, in 10 meter increments.
Otherwise, it's only meaningful in terms of comparison to each other
Also, I doubt these are correct scale the ships appear in the movie regardless of their dimensions I doubt the Conestoga ships are that size compared to the Covenant or the Nostromo. Also the Covenant and the Nostromo have 3 decks apiece, that appears to be anomalous in this diagram, too.
I'd draw the Covenant much bigger and longer. I guess you're getting the dimensions from 'official' sources; but these look scaled incorrectly. I would have drawn the Covenant at twice the length of the Conestogas. ...or maybe scale down the Sulaco and Patna by half, making them the size of the Nostromo.
