I don't remember seeing this mentioned, so I was just about to ask if every shot on the roll looked this way, or if there was any strange marks on the leader and between the frames (the unexposed areas of the film).

I think the shot you just posted makes it a developing issue; where the film may have not been wound on the reel properly. I'm not an expert so take value of this diagnosis for how much it cost you...
