Don't know which made me more excited, the first time i developed my own negatives (135 in Germany, not knowing what the heck I was doing) or the first time I developed 4x5 negatives (at NESOP taking my first professional class). Oh yeah, my first 8x10 was pretty exciting also.
Maybe a tie. I like your enthusiasm. Don't get carried away with more development, it makes the negatives harder to print. Those negatives look pretty darned good for your first efforts and using outdated film.
Get some real film, somewhere in the 100 to 125 speed range and perfect your development technique. And... go out and shoot. Lots.
