Good job, especially for a first try! 🙂 There are a couple of older threads here about astrophotography and stacking that you might be interested to read if you’re getting into astrophotography. It seems like there should be one or two more, but I can’t seem to locate them… 🙁

I don’t know if you’ve ever heard of Nature Friend Magazine, but they have an online presence where people can share their astrophotography shots as well, if you want some inspiration. 🙂
