Great stuff!
I ~think~ I remember you from back in the day, I was just a wee baby artist back then tho so I doubt you'd remember me, I can't even remember my username lmao (I think it was pixeldragon or something dorky like that).
Latest piece is looking really nice there, i'm not going to be able to comment much until it's more polished as landscapes like that a bit above my skill level. The only thing I can think of at this stage is that the moon is a touch distracting.
Composition-wise I think you're close to the golden ratio in your focal points, which is looking lovely, the only thing to break that is the moons placement and brightness. So you might want to watch that, or perhaps tone it down a shade.
As an aside, you might be interested as a digital illustrator in Fessler's indexing approach(
