Yeah, artifacts, slower renders, and rounding errors.

However...

4.5 hours for a cell phone sized print is going to leave you stuck if 
you ever want to render at a decent size, but a gallery scene like this 
one should be "fixable." Decimation would improve the speed, but you'll 
need smooth triangles for that.

Complex mesh scenes may be a dead-end in POV-Ray. Sure, one can have 
dozens of plants or cars or people, but that's not the kind of 
complexity I'm talking about. I mean that one cannot have dense meshes 
of any sort arranged into a complex "scene geometry." At least, none of 
us has (to my knowledge) ever figured out how to do it. Or none of us 
has a sufficiently powerful computer. That leaves many of the advanced 
users chasing their tails. Put some effort into improving the render 
time of this simple scene and become one of the truly elite POVvers 
creating printable images.
