More playing with Bezio style maps

I've been quietly working on some things and removed myself from many of the social media platforms I used to haunt. I've been paying around with more Bezio style maps as 1) I like them and 2) they're easy as snot to make.

So here's a little sneak peek. In looking at the map and how I might be able to produce a map that is easily used in a VTT while keeping some things secret, I came up with the idea below. If you use vision blocking in roll20 he should be easily able to hide those pit traps and that secret door among the regular walls very easily.

I've also started annotating on the map which doors would be locked eye drawing a little key inside the door symbols, as above. I can see where some DMs would not want this on the map, but I think that's an easily enough thing to overlooked or hand wave in game.
