Thanks. To me it looks pretty simple and amateurish, but then I'm the one who built it, so I'm going to be more critical of my own work. Although it looks fairly simple, it took a tremendous amount of time to get every detail just right, for example turning off snap and spending 5-10 minutes very, very carefully aligning certain blocks. Since it's an angular rhomboid shape, any imperfection is very obvious (and there still are a couple).
It also took a bit of optimizing to make it a viable and powerful freighter. I actually didn't want to add nacelles, but you need maneuverability and I didn't want to break the lines of the hull's shape either, so I finally caved and went with nacelles.
