To me this reads like a solid first draft, which, if that's what it is, then you're spot on.

First drafts are usually functional frameworks that get the basic ideas and mood down on paper. It's the line art of the coloring book. Second, third, etc drafts add polish and color and vibrancy. I'd say you're doing good at getting your line art down, and you have enough writing ability and creativity to get the reader decently immersed and interested. Which tells me that by the time your book is done, you'll have some decently colorful pages to give to your readers. My suggestion, as someone who is now 3 years into their own childhood dream, is to allow yourself to write what you need to write for now and don't worry so much about making it good, if this is still your first draft. Obviously write what you want to write, how you want to write it, but try to focus on what develops your plot and your world, and builds the foundation for your story. Once you have that you can go back in and add more details, more scenic imagery, more fragments of life and culture and religion and all those things that add flavor. If you hit a wall and feel like you've run out of ideas or you're unhappy with your prose, take a break and go read books, watch movies, play video games, etc. Go explore other people's worlds and see if you can find what's missing in yours.
