It is hard to tell at such small sizes, but my observation is that you pulled a lot more detail out. Look at the shadows, you have detail, they have black. You could make a choice to place the shadows darker, but that would be a creative decision. At least you have the info in your scan to make that choice. Also, look at the detail on the instrument. Yours has more detail. You do have a green color cast on my monitor. I'm on my laptop right now, so not sure if that is your photo or my monitor. You could fix that green with a simple curve adjustment. It looks to me like your lab did ok on the sharpening. When I had my film scanned at Walgreens, they sharpened the heck out of it. Your lab scan looks to be of a pretty high quality.
