I've got a multi-stage plan for this part of the project. In order to avoid too much festering and time-wasting. Stage 1 is the longest (current stage); pour in tons of non-specific junk in there to get the composition nailed down.
Stage 2; spend a couple of days putting in the more fun, imaginative details. There's a boatload of shit in there already, but it's all pretty white-bread.
Stage 3; make the details for scene segues, that'll be separate, higher-res files parented to the main file.
