Intriguingly shot - I like this. It's an effective use of under-x. There's a touch of lightness near the thumb which looks odd, and the set-up feels a little forced perhaps but these are pedantics. Hope you fare well (and I love the light bulb).
While the monotone image with colored object is a rather passe' style having seen this technigue in every challenge, in this case it works because it's so different. The matching color and tone of the light and glass are perfectly complimentary to the Victorian silhouette feel of the subject. No major technical issues and artistically impressive. Well done.
