This was the level at the blockout stage, using the Creation Kit I added in the main ideas for the layout of the level and how the player should move through the dungeon. I didn't have all of the design ideas fleshed out yet, but I had a direction that was intended.
This was the level at the first iteration past the blockout stage. This was after a play test so I was able to take feedback into account for the design. I was also pushing forward on my intended design fleshing out the areas breaking up sight lines so the playspaces can feel less open and unfilled.
This was the level at the final milestone for the project. This is where I was able to finish up much of the design ideas and flesh out areas to look nicer, have better bread crumbs and points of interest, and making sure things felt lived in and less empty.
