artistic improvements

Shen and Zhao. They first made a splash as an "athletic" team with huge, solid throws and twists and SBS jumps, but were considered lacking in artistry and musicality. They later made huge strides in this area, developed a strong connection between the two of them, and delivered some of the most memorable performances in pairs skating.

Before (1999 Worlds)

After (2003 Worlds)

Yes, perfect example. Their whole career is a big artistic improvement.

The two best examples I can think of as well: Shen/Zhao, and Michelle.
