Agree with above, I like your "accidental photo".

BTW.... I have NEVER had a "bad roll" of film and I used to run 80 a week or more through my gear for years on end.
Miss-handled film is another thing... too many times is the hot trunk, airport scanner, etc.

Developer may have had stuff settled out... check the jug, anything more than a month for D-76 mixed especially with any air in the tank will cause underdevelopment... (my experience)
