Narrative:
At approximately 1;200 MSL; I broke off the ILS to 22R and began my circling maneuver to runway 29. Runway 29 had been programmed into the fmcs with a 5 nm runway extension. On downwind ATC directed us to start our base turn inside the 5 mile fix. Once established on base leg; I could not see the runway from my seat; so I started a turn toward the runway and began a gradual descent. Since much of my attention was devoted to trying to locate the runway; I descended lower than I intended. When the GPWS obstacle warning sounded; we initiated a go-around and landed on 22R. In my 14 years as captain on the 757; this was my first circle to land maneuver. In hindsight; I would have made a three mile fix and [used] lnav to the fix.
