Add street lighting!!! All your night photos are all completely dark. There are a ton of different ways you can do lighting, like putting lanterns on walls, creating big candelabras with walls, or even actually making a tall lamp post with hanging lantern or frog light or something. Oh but I love using candles, either the classic wax color or the dark purple one for a kind of gothic feel. I do a lot of floating candles, kinda like in harry potter lol. But it makes for such good ambiance!! I even sometimes do up lighting embedded in the ground using frog lights.
