First time Ming Aralia owner

I've done some browsing regarding ming care, i know not to move it from where I initally set it, I rotate it once a week for even sunlight distribution, water when the too few inches of soil dries (checking via moisture stick, finger test, and weight test). I know this is posted during winter/cold months for me, but i try to keep my humidity in the room around 45%-50%, I also keep it away from where cold drafts would hit it. I try to trim the yellow leafs off as frequent as I can.

I feel like its losing a lot of green leaves, am I over thinking this one or is my plant still looking healthy for enduring the winter months?

PS. I am very new to plant care. Thank you for your assistance and consideration!
