Book cover design for a sci-fi novel!

Hi everyone! 🤸‍♂️

I'd like to share this piece of work with you that I designed for myself two years ago! However, after some time, I purchased a book titled "The Moon Is a Harsh Mistress" by Robert Heinlein. This book is a sci-fi novel. I'm quite interested in its story, and I decided to make some changes to my work and turn it into a book cover. I hope you enjoy it..
