Notes on my Fiddle Leaf Fig

My Ficus lyrata has been with me for about eight months now, and I finally got it to stop dropping leaves—turns out I was overwatering like crazy. I moved it away from the heater vent and let the soil dry out more between waterings, and new growth started appearing last month. I'm still nervous about the brown spots on a couple of leaves though. Does anyone know if those are normal or a sign something's wrong? I'd hate to lose this one after we've finally made progress together.
