It’s looking good! I have a similar problem actually, and I’ve been noticing that my older leaves are also slowly deteriorating as well making the overall plant seem a bit less nice. I ended up chopping some of the vines back almost all the way to regrow some new branches near the bottom to replace the old leaves. You can probably do the same over time with all of them to keep them fresh.
Fancy! This looks like it came from one of those collector edition sites for books! Definitely a pretty piece to put on the shelf.
