The Starship launch was a huge success but there is still much more to be done.

SpaceX is adding another ablative heat shield layer underneath the tiles and the heat shield tiles will be made thicker with twice the heat resistance. The heat shield tiles do not need to be made twice as thick for twice the heat resistance. It will likely be adding about 20-30% of the thickness.

SpaceX Starship being able to successfully go to orbit means Starship will already be useful as an expendable super heavy rocket.
