New player here, how did I do upgrading Silverquill Influence?

Hello all! I just got into on paper Commander, after years of friends of mine insisting I do. I used to play Digimon TCG, but since it is in a bit of a bad state, I thought I'ld have some fun with Magic. I have previously really liked Aura decks, namely with [[Ellivere of the Wild Court]], but with these new SoS precons, I really found Killian's to be such a unique and fun twist, and I decided to try it out on TTS. I had a blast with the deck, I found it very interactive towards other players, and, though it is not the strongest, I think I can still manage to win a 1v1 with a hypothetical voltron-esk strategy.

With this said, I do think deckbuilding is part of the fun of TCGs in general, but, being a complete noob in this game, I thought I'ld ask for some opinions among you, more experienced folk. I have a lot of doubts about what I made, namely whether I have enough recursion / card draw, whether I have enough removal, whether there are key enchantments I missed, even whether [[Eiganjo Dynastorian]] is worth including, among others. Do note I tried not to blow my budget away, and though it will not be the most competitive, I am still trying my best to solidify it somewhere in Bracket 3? (I'm not sure I understood brackets properly)

In the sideboard, I included some other cards I considered but am not sure whether should be included. Thank you so much for checking this out, and thank you for bearing with me at the start of my journey!
