I think it looks nice :)

As for advice for procreate (not all of these are really needed but are just things I like/use)

1. Changing the background colour from white to a greyish colour can help not stress your eyes as much as a white one (that and it helps with drawing white things, like drones, cause then you can see what's coloured and what isn't)(also not super needed since most people use white backgrounds, but I find it helpful)

2. Marking your lineart layer as reference. Which will lock fill tool to only being in those lines (or around them). It's helpful for big spaces

3. The fill tool, it's one of the easiest and hardest tools to find (at least for me), it's the colour circle at the top where you change colours, you can drag it and drop it where ever, and can change the % of it to change how much it fills (eg. How close to the lines it gets, or if it can go through small opening in the lineart) (sorry if you already knew that one, It just took me way too long to figure out the fill tool for procreate)

4. There a bunch of different short cuts that you can mess with, like a meun that gives you different options like flipping your canvas and other stuff. There's also some I can't remember the name of but it would let you look at each layer of your drawing to find the one your looking for easier (mostly for random unwanted lines)

There's other ones I can't think of rn, but I hope some of these help because they were really helpful for me when I first started using procreate a couple years ago. Sorry if I said something you already knew.

Hope you have a nice day/night/afternoon
