good of you to take such an open approach and invite comments.
There are things in this picture that - when put together - prevents me from being "moved" by it:
1. The highlights are blown a bit - i.e. the centers of the light sources are perfectly white blobs
2. The picture is somewhat out of focus - looking down the vertical lines, I see some camera shake
3. The white balance makes the cast light in the ceiling look a dreary and bland beige
4. Composition-wise I think that Tomas said it well. I'd add to this and encourage you to ask yourself "why" have I taken this picture?
- is it a story about dramatic colors (it could have been, if the colored parts of the glass too up more of the frame and were more "punchy".
- is it a story about dramatic casting of light? (it could have been if the light-play in the ceiling had been the focus of attention in the image
- is it a story about an interesting design of a lamp? (it could ahve been, if the lamps were a little more special or unique or dramatic)
- is there some emotion we are supposed to associate with the image? (it could have been of the light and color range was wider and more dramatic - e.g. if it was very light on very dark.
A picture is also about context and understanding. If these are some kind of ultra rare medieval hand blown former torch covers that hung in Alexander The Great's dining hall, I wouldn't know to recognize it - whereas some antiquities expert would foam around the mouth seeing them. I could be one of those audiences who just doesn't "get it" - the same way some don't "get" Andy Warhol (I'm one of those too).
Is this picture bad or good? It's in the eye of the beholder. If it has a special meaning to you, it's a good picture.
Are there way to present these same lamps in a photo that would make them more interesting to an ignoramus like myself? Yes, absolutely! Better focus, color, white balance and composition could make these lamps seem very fascinating to even the most casual observer.
Keep plugging away at it and enjoy the process. For even the best darn photographers in the world, only one shot in many is truly remarkable. For chumps like me it's maybe one in 500, for better photographers it might be one in 50.
