Haven't decided yet. I really want to finish the bridge, but my motivation for making more display screens is at a low right now. I still need to model the chairs as well.
I've thought about modifying my existing TSFS tricorder and communicator to be how they appeared in both TFF and TUC, which would require minimal rework since they were basically the same props with just slightly different details and colors.
I also want to go back and touch up my exisiting TUC corridors to be on par with the quality I've set with my TWOK corridors.
I have a secret desire to move on from the Enteprise and explore a few interiors of Sulu's Excelsior, as my motivation has been shifting from just re-creating stuff we saw in the films to exploring the things we didn't see but always wanted to. My stint with making those non-canon TOS ships has really given me an appreciation for exploring the stuff we never got to see.
