The Int was indeed zoomed in a little further than the VSD. Still, it's notably longer but looks about the same breadth in profile (it's shunted a bit. I did my best to replicate the new perspective but it seems FFG changed the angle a touch in addition to adding a shadow around the newer picture bases). Anyway, sorry for the ick photo, still toying with GIMP while I'm reinstalling photoshop.
Nevertheless, the Interdictor is a fairly sizable cruiser.
So a 600 meter Interdictor is longer than a 900 meter Victory... hmmm...
Also thought it looked a little too big. I can throw an old Star Wars Starships Interdictor on there if I want a comparable size that's more accurate.
