They look good. What border size are you using? I tend to stick with 0.70 so they don't take away from the main focus of the picture.
I've noticed this too, i can never get the resizing correct!200 px so it probably is just a fraction large on portrait style shots. Better with the landscape. I'll amend on any future albums. I don't know if it's the forum, but sharing at smaller sizes completely screws the sharpening - makes them oversharp compared to flickr.
