Hi,

Some of the tokyo gardens are beautiful and well worth a visit. But as other posters have mentioned, there is probably too much in it.

Whilst tokyo skytree is impressive, you may not get the best views as it is a bit away from the main tokyo attractions . ( I would tie in Tokyo sky tree with Senso-ji- & asakusa as they are close by). Views from Tokyo Tower or Mori tower in Roppongi are better as you are closer to central tokyo

It can be worth taking it slower and exploring attractions in more detail ( ie there is always lots to explore in the Meji-jingu shrine and park, imperial palace gardens etc) rather than rushing from one place to another
