Problem topology. Two edge loops, one supporting the outside rim, the other the left inside rim. Needed an additional loop to support the right inside rim.
Solution topology. I repurposed the outside rim to also flow into left inside rim. Ngons allow for more than two poly flows, enabling a greater degree of control.
Smoothed (subdivided) result of solution topology.
Here's something I did just now. I needed to make this corner sharper but didn't want to add another edge loop (would have meant more work), so what do I do? #ngon to the rescue, of course. It smooths *really* nicely too. Alt text for more info.
