Rescanning - Nikon Coolscan IV vs shop scans

Back in 2011 when I was just starting out with film photography properly, I had a roll of Fomapan 400 developed at a local photo shop - just a little one, next to my then-office on Brick Lane, run by an older guy and obviously geared up for holiday snaps. Must have cost around £7 or so for a black and white processing, and scans on a CD. I liked how they came out, but they were rather small, and I'd like to get a couple of them printed up properly someday, so I decided to re-scan on my little Coolscan IV.

Quite a difference, especially on the last photo! I'm not sure if I prefer all the new scans - the old ones (whole set viewable here) are more dramatic, but have a lot less detail in them. Maybe more tweaking needed before they're perfect!
