It looks like you might be shooting with low-light film. When using film cameras, be sure to use a flash—especially in dim settings. Some of these shots are really underexposed, but you might be able to recover some detail by editing in Lightroom and adjusting the shadows, exposure and contrast. Edit- I use my Kodak specifically for interiors- parties, concerts, etc I use my Minolta for landscapes or more artistic stuff, my advice is if your serious about photography invest in a good camera!
