This is my second roll of film on a completely manual camera, and I'd appreciate some help. I'm using a fairly old camera (I think), a Zenit Em with the lens it came with. The roll was an Iford HP5 400

I'm not sure if the photos have noise from the scanning process or if what you see is film grain. I didn't do the scanning myself; it was done at a lab. I'd like to hear your thoughts and I'm open to criticism, and I'd like to know if I should improve my exposure technique or if I should find a different place to have my negatives scanned.
