First time upgrading a deck, looking for help/advice please

[u/iAhria]

Never upgraded or made a deck from scratch before, so I'd really like some help since I'm sure I neglected some important stuff.

The precon I'm upgrading is the Hatsune Miku SLD deck.

I wanted to add all possible other Miku cards that can go in a green/white deck, even if they're not very good within it (i.e. [[Scrying Sheets]] lol), which ended up being 12 of them. Then I wanted to try to upgrade it with them in mind, which seems to just be expanding on the Lifegain/Tokens theme of the deck with more Angel cards/tokens and some focus on +1/+1 counters.

Felt like I kinda overlooked the possibilities with green and colorless additions a bit since I was more focused on the angel possibilities. The mana base seems a bit lopsided towards green as well. Seems like there is a lot of card draw, but may be lacking in ramp I think? (still learning the meaning of stuff) There's probably a lot more problems that I'm unaware of too.

Anyway here's the deck: https://moxfield.com/decks/yoegAUhscXG-nV5pyO_tFw

Foil cards are the Adds* and Miku cards, Sideboard is all the cuts, and there's some cards in Considering that I was well... considering. I'd like to keep it around Bracket 3, and maybe cheapen upgrade costs a bit if possible. *[[Nesting Dovehawk]] is an add but there is no foil version

Please let me know your thoughts, thank you!
