Since I'm almost finished with the secondary hull (the only thing I need to do now is texture in the deflector trench and quantum torpedo bay/captains yacht and windows) I'm going to work more on the model.  Save the bottom saucer texture for last.  I'm working on making the detail on the bottom saucer (those little raised details that were originally textured in).  This would add a few hundred polies at least, I'll have a final poly count once I clean everything up (ugh, something else I need to learn about modeling...).  Then once I finish with the saucer section, I might work on making new phasers since everyone doesn't like the originals...
