That is a good first image!
Everyone has added some really good things to think about so I'll add something a bit different. I think before you start AP you kinda think "ah, I can take images with my camera so I can do space right?" but there are so many factors to take into account that will only come with just practice and a hell of a lot of patience. Try not to compare images too much with other peoples are every one has a different idea on what and why they like to capture images/how long they have been taking astro images and what their equipment is.
Get used to checking the weather all the time, haha.
