Making a modular underground industrial kit

programmer23

Hey guys, haven't posted here in ages, but getting back into this life.  Working on a modular room kit for a game project that's trudging along.  I would love any crits or suggestions on what I can improve on.  

I am creating this three-way join piece and wanted to know how the topo looks or how I could improve..  not sure if I should have run another edge loop along the back there.  Everything looks fine, but don't want to build bad habits.

Thanks, everyone, stay safe!

There is going to be this massive missile silo thing on the ceiling, maybe about this size or a bit smaller on screen.  This screenshot is of the "low poly" version of the model (About 9.4k tris).  For something this far away, that will not have any real smaller details, is making a high poly necessary if the low poly looks good?  Thanks, trying to slowly learn all this, haha.
