Oh my, your first ribbon! Congratulations and way to hang in there - 160 challenges. This has great design elements and I love the tones. I do think willem has a good idea . . . but for now, just sit back and enjoy :)
Great patterns and nice high contrast. I suggest to crop away the top 10%, i.e. to remove the two white parts of the top left balconies. They seem to break the pattern.
