What went wrong?

[OttawaGoa]

these were both taken at 12:00pm and I used my vivitar 75-200 mm telephoto lens with a pentax MZ-M, I had never taken night shots before so my apeture size (the one on the lens that governs how big of a hole light shines through.. is apeture the right word?) was the 2nd lowest and 1st lowest for the crappy one (5.6 , 3.2). As well it's really blurry for me.

Would those have turned out semi decent if I used a higher apeture number? (Maybe 11 or 8?) And my shutter speed was at 125 with ISO at 100 +2 (maybe the film, shutter speed?)

Thanks in advanced!
