Hi, amateur modeler here. Just thought I'd share this starship model I made recently. Full 3D view can be found here as well as my other (less detailed) designs: https://calculusmaximus.artstation.com/projects/aRBB6k
Edit: I smoothed out the faces at the request of evil_genius_180.
This is the third version of my Corvette class starship, a TOS-era Star Trek starship. The Corvette class is a small corvette (who would have guessed) meant for scouting missions and ferrying envoys and precious Federation cargo, and is capable of self-defense. It can carry out limited scientific missions but is not capable of extended deep-space missions due to its size.
This is just a rough concept model, but it's probably the best I'm going to do at my skill level, and better than anything I've done previously. It's got some horrid topology and lacks textures, but since this is a personal project more than anything I don't mind. Suggestions are welcome.
You could try doing skewed windows, like a parallelogram shape. I guess it all depends what room the Starfleet Design Bureau wants to cram into that small space.
