Sorry should have said - I used a Bronica SQ-Ai with an 80mm PS lens. The photos were scanned by the lab (Photo Imaging North Wales). The EXIF says Fuji SP-1500. I have put the full size scans on my Flickr page: http://www.flickr.com/photos/59846163@N07/
I like the first one, it's nicely composed although at first I wasn't sure if the square format suited the scene. Is there a slight colour cast on it?
Second is OK, although I'd be tempted to get rid of that shadow in the bottom right hand corner.
Third I'm not sure about.
Fourth is very good, lots of depth and nice colours, suits the format well.
Fifth works really well too!
