I love the texture and the presentation of the first two photos. But the objects being photographed aren't anything special and it seems like you weren't really focused on what you were photographing so much as you were with how you presented those photos.

I think that the 4th photo is the best. It's a great macro shot with nice composition and perspective. The grain also works really well for that kind of black and white image. But yeah, kudos on using film and developing your own photographs. Too many photographers these days are hung up on digital and don't learn the basics techniques of film and darkroom which is really a shame.
