Got my outdated Velvia processed that I took in Brick Lane, London. i rated it at 32 ASA . I have shown a few B&W on OM-1 and Nikon L35AF from the trip previously. i like the way even the Rubbish Bins ( 'Trash Cans' in American I believe) have been painted !
For a more 'Neutral Subject' do you mean buildings and roads ? There is a slight Magenta cast with outdated Velvia, easily fixed in FastStone Image Viewer in Adjust Colours -- I add a small amount of Green.
