That's a LOT of work for a few quick encounters. I could understand the miniature terrain better in 3e, 4e or Pathfinder, but 5e really shines with theatre of the mind.
Nice terrain though - very nice, in fact!
It is a lot of work for just a few quick encounters, but I was working on printing my base set of tiles. They will get reused over and over and starting with Redbrand Hideout gave me a really good set to start with. I agree that 5E shines with Theatre of the Mind and for some encounters we do skip the terrain, but we really enjoy the visual aspect of it also.
