Usually I do my best to re-create original vibe of the ship + additional, cool stuff like some lights and greebles. Sometimes there are cases when I find quality of original asset not sufficient to provide me with clear artistic destination, like Aeolus or Hecate. In such cases, I go for more artistic freedom and reimagination.
Orion is not one of the bad quality assets like Aeolus or Hecate [where I love designs, but vanilla assets quality was poor], so I will do my best to re-create both original vibe and enchance it with flavour or Bobb's Orion. So yeah, expect tons of lights :].
