Shooting with the wrong exposure readings

I shot these a few weeks ago in Portugal...it was early in the morning before the sun had risen and so was still a little misty. I was using Kodak Portra 400 with my Hasselblad 500cxi, but like an idiot I had forgotten to change the little cardboard tab on the back, so I was in fact shooting with Portra 100 not 400.
All of my light meter readings were wrong, and to add to my woes I forgot to wind the film on fully before opening up the back...this comes from shooting with two backs and wanting to catch the mist before the sun came through the clouds.

I have to learn to slow down and be more careful. I'll post these photos and wonder what could have been...and hope I get better at this photography thing.
