A quick look at a schematic like representation. I think I have only a few small bits of detailing to go before moving on to signage and colouring.
Going forward I'm trying to be mindful of what bits I add other than the standard signage and windows and lights. If I clutter it too much then it doesn't look like it could be in the same familiar TOS universe. I feel I need to add a bit more in surface detailing, but I'm presently pondering what that little extra might be and still maintain the right look (in my eyes anyway). Sometimes I try something only to discard it when I doesn't look how I had envisioned it, but then that can also give me a better idea of what can work.
