Hey, thanks for posting your work, it looks very appealing like a snapshot or something of a time past, I know with my own work, I always spend a lot of time deciding on the range of colours or contrast, etc between the midtones, highlights and shadows,("colour theory"
) there's a few ways to easily adjust the levels on different programs, but I recommend looking into it, I adjusted the photo below to explain what I mean, think the one I used makes the blacks blacker and the whites whiter, and makes the saturation of colours stronger
later!
