Look out for cars, they're dangerous.

Golden hour ftw

Do it at night after rain (idk I'm not a photographer).

Sometimes you can find a deal on expired film. That allows you to shoot more. The more you shoot, the better idea you’ll have of the qualities of your camera and film.

50mm is generally a little tight for classic street photography, but it’s fine to get started (27 to 35mm is the sweet spot). People will argue endlessly what counts as street photography, even though it has a clear definition: candid moments on the street involving people. A cityscape or car is not street. Two people laughing at each other is street. A closeup of an interesting face is street. A person aware of being photographed, posing for the camera, shot with a blurry background is a street portrait. Get close (your 50mm makes this a bit more comfortable, but you get a different look). You generally want at least f/5.6, but ideally tighter aperture so you get most things sharp. Good luck!

Watch your edges, having incomplete or sudden additions of geometric shapes can throw off the focus of a photo. In contrast to nature/outdoor photography where nothing is the same twice, use the advantage of static objects to really frame your shots how you want them to be by scouting locations at different times of day to see how shadows and light will work in or against your favor. Have fun though, explore the corners of towns that others may overlook!
