Would definitely NOT go with a 32", the 30" is fine. In all honesty, I was thrown by the front-facing picture, and initially thought, "wow, 30" is still too long", but it was an errant interpretation. One, the pants are clearly casual (no center crease), and if there were one they'd still be a good length. No, the part that seems "off" to me is that you're pretty slim (you put your measurements on another post somewhere), and these pants look to be a rather full cut, versus "slim" or "tapered". I'd suggest that a slimmer cut pant would work better on you, lessening the "swimming in the fabric" impression one could take from these pictures, esp given the otherwise slimmer fitting t-shirt you're wearing.
