Terrible Pakon scans, guy who did them says it's my fault

okay so uh, I've been scanning rolls with my girlfriend's 60D and my nFD 50mm 1.4 handheld on top of the mount because I didn't have money for real scans. Now I do, and I brought them to this guy who has very good reputation, at least on his Facebook ratings, and has a Pakon F-150+. Thing is, they look like this. The guy has said it was, in order, my screen, my exposition, the fact that I pushed it, the (generally well-regarded) lab that developed it. But I'm not so sure: why do I have WAY less contrast with a simple 60D? Why can I recover detail that absolutely isn't there at all with high-grade scanner?

1. Canon 60D + handheld nFD 50mm 1.4 backlight by a laptop screen (hence the pixels; the plastic I put behind wasn't enough, I noticed later), raw developed with Neutral camera profile, exposure +2.10 (photo was taken too dark, hence the noise), Shadows +52, Sharpening +51, and no other changes
2. Pakon F-135+ full-res TIFF scan
3. Same scan developed in Lr: Contrast -100, Shadows +100, Blacks +100

It's not allowing me to edit the post, so I'll make corrections here:

1. Untouched Pakon, 2. 60D, and the one I'm attaching here is 3. the processed Pakon

Thanks all!

Sorry, I wasn't able to display the images images you posted. I'm guessing that's why no one else responded.

Reputation and facebook don't go well together.

Open images in new tab to view them. They are poor scans by a poor scanner simple as that.
