Rin and Seri - First deck help

Hello!

I am pretty new to Magic. I own a couple of precons but I wanted to build a dog and cat deck that I could give to my partner for her to give Magic a try. It was not meant to be an overly competitive deck but I found a couple of very nice cards for a good price. Looking for some feedback on whether this looks good and will hopefully play smoothly for a beginner: https://moxfield.com/decks/kcERuVzv6UuLh1Le1bIp8Q

I think it may need another land or two but not sure what to remove. It may also play better with one of the other Legendary creatures as commander but that is something to try another day. I also purchased too many cards (see Considering) that could be swapped in if it would make the deck more fun.

I appreciate your time and feedback!
