I think a couple of the portraits are a little too dark. I get what you were going for, but I don't think it works as well as it could. It also looks like you have some film scans that are really really dirty. Make sure you clean em before you scan. It generally takes away from the photo. I'm not a huge fan of the low-contrast stuff either. There are a couple situations where it works, but it doesn't look right to the eye in most scenes (unless those shots were shot with a low contrast film, in which case you can't do anything about it). Overall your work is nice though! Those are just some small things that might help you take it to the next level.
