A lovely shot Jon, good resolution, so your focus and colmination are pretty much spot on. I'd just watch your black clipping when processing, as it's always tempting when you're starting out to think you need to create a black background but sometimes at the expense of losing faint detail. After all, the night sky is never really truly black, so you can afford to ease back a bit in the background. Other than that, the colour looks great and noise is certainly well under control. Well done, I would be very pleased with that result. You are learning quickly.
