On the practice grounds of the Wonderbolt Academy there stands a statue that looks out watching as the recruits practice, struggle, and push themselves further than they thought they could. It's brown, patine bronze form seems to be judging the recruits as they go through their drills. Encouraging them to achieve greater awesomenss!
Just as the Royal Sisters have had various artifacts constructed to honor their contributions to Equestria and Twilight Sparkle and Cadence have been recognized for their achievements. I could see the Mane Six getting similar accolades.
