This photo works well on so many levels, and provokes a great deal of thought.
The first and most significant thing that comes to mind is symmetry, which in itself is a thing of beauty. The perspective from which this was shot really helps to convey the idea that the whole building was likely designed with symmetry in mind.
The lighting in the photo is very well utilized. My eye is drawn first to the light coming from the front door, which immediately gives you that sense of symmetry. The light in the side windows helps to draw attention to the walls.
The title really speaks to me and is highly descriptive of what has happened to this place. In multiple ways it is made clear that, while it obviously is still beautiful to look at, this building was a lot more so in the past. Not only in the sense that the building is now in disrepair, but also that the symmetry of the building has been lost, with debris scattered about and the color of the walls and ceiling being faded off in places.
The attention to detail and the color contrast also help to tell the story of this building. The walls and ceiling look like they have been discolored from fire. This is reinforced by what looks to be ash on the floor.
Ive seen several paintings like these before, with a time lapse theme. I have to say this one is well done. The top, while richly decorated with a beautiful and colorful ceiling, pans down to the inevitably bare and empty room it is today.
When looking at a time lapse picture like this, I tend to focus more on how well the transition from past to present is. In this case it is very subtly done, a patched part of the ceiling here, glowing windows that would normally be half broken there. The eye is always immediately drawn in lapses like this to the more colorful part of the drawing, and the lining in the ledges pointing to the center in this one draws the eye back down to the parts that are empty, and thus into the less fabulously furnished piece.
As for painting detail, the ornamentation and decay of the room really stand out. Some artists will sometimes botch a job by using larger brushes to do a watercolor with, and with time lapse pictures, that tends to be a drawback. Not so with this one. I am impressed with the minuteness of the detail, even right down to the filings on the floor and the subtle shadws on the walls and floor. Not to mention that beautiful blue dome.
In summary, while not terribly original, the artist does a decent job portraying the piece with an above average amount of detail and lighting use.
I am always astounded that you find such amazing buildings - and they're still so "together". I would think that they'd have been taken apart for all the marvelous architectural detailing pieces for use in other places...but have to admit I'm really glad they haven't been 'cuz then we wouldn't get to see them in your stunning photos!
