Alot of Voyager's CGI is terribly dated by now. All the models of species 8472 are incredibly CGI looking for one. If it were a completely animated show they would look great, but blending with real life shots it looks horrid. In the first couple of seasons even the exterior shots looked like they were from a video game, but they started improving those at least later on.

They did build a physical model of Voyager. I didn't think it was augmented by the CG version until later in the series?
