I like the way flash creates a tension between camera and the subject. It is pretty aggressive in a way but I want to experiment more. I hope I won't end up in a real trouble.
... even in the dark, there are enough clues in your third picture to determine that you were standing outside 86 Cheapside!

Nice photos.
As long as you remember that when using flash you have two exposures to deal with - ambient exposure and flash exposure - and that up to the flash sync speed shutter speed has no affect on the flash exposure, only the ambient exposure then using flash is fairly straight forward in getting the shot you want.
Keep experimenting. Some amazing effects can be created using flash, especially off-camera flash.
Yes your guess is correct 👍😇
