That is some impressive modeling and lighting. Am not familiar with the Lukari, so cannot speak of the likeness, but this is craftsmanship anybody with eyes in their head can appreciate.
The light streaky stuff is all produced by the renderer. It's supposed to realistically generate them according to how bright that surface is lit. There are a few settings about what kind of streaks you want, but that's it.
That looks really interesting. Quality is simply astonishing and an eyecandy. What universe is that kind of ship from? I cannot remember to have seen it in Star Trek and i'm not familiar with other sci-fi series.
