I think it's great, and I admire you tackling a challenge. Your workmanship is lovely and personally I've always liked dark backgrounds.
When I look back at my projects I have a rating system, one is for "did this meet my mental image of what the project was supposed to be" and often that has a higher rating for that than "do you like it". But sometimes, "did you have fun making it" is the highest rated category -- which is better than when that is the low score!
My latest project is also a challenge for myself when I picked up a bag of scraps that I would never had collected on my own but I could see worked as a whole. It's good for me to stretch myself every now and then but I'm quickly retreating to my comfort zone for the next project or two
