Hey, looks good.

Consider adding Estrid, the Masked? Her +2 ability is great with the enchant land enchantments (untap them to make more mana per turn) and her -1 makes an enchantment mask which can pump Tuvasa or protect Tuvasa if you mask her. As long as you have counters on Estrid you can make a mask. This can add up very fast because each mask is itself an enchantment. A mask can go on any permanent this can also help to protect your enchantresses.

Consider Overgrowth? It's one of the powerful enchant land enchantments because it can make three mana when the enchanted land is tapped. You make any color of mana that the land can produce and then because of Overgrowth's ability you also make an additional two green mana. Trace of Abundance is a good card, but unfortunately you can can't play it in this deck. The color identity of your Commander is only Bant (green, white and blue). Trace is red, the hybrid mana symbol makes it a red card, a white card and it's also a green card. Can't play red cards with a Bant Commander.

Consider Mystic Remora? Remora is a very good enchantment in Commander, it's a one drop and it's upkeep cost is easier to pay for you with the enchanted lands. additional mana is a lot of mana your opponent's will have to add if they don't want you to draw card when they a cast a noncreature spell. Your opponents will most likely ignore this thus you're drawing cards simply by letting your opponents play the game.

Good luck with your deck.
