Hi Raj, I think distortion can work but maybe not so much with a straight-on shot such as this one. As this building is symmetrical, I would tend to shoot it symmetrical unless there was another shooting angle that produced a more compelling image.
For the sign, I frequently snap a separate image of the sign as a reminder of the pertinent facts associated with the subject. Once I have the image ready to post, I then use some of these facts as descriptive text to enhance the viewer's appreciation for the scene.
You are shooting into the sun. Is there a shooting angle that would cause the sun to form a glow or halo on part of the structure?
For a change, avoid shooting from YOUR eye level. Everybody does that. Experiment with high and low shooting angles for effect.
It is also a good idea, particularly if you can return for a reshoot, to make notes about conditions that might enhance the scene. One thing to consider is the condition of the sky. Would the tomb look better on a dreary day or a sunny one? With or without clouds or shadows? Would it be a better rendition at dusk or dawn during the Golden Hour or perhaps during the Blue Hour?
Just some 'what if' thoughts...
How would it look at dusk with a full moon rising above and to one side of the tomb? Or perhaps, with a special event that is associated with this structure? Is it possible that after a rain that there might be puddles about that could serve as mirrors and produce reflections of the tomb? What about with a thunder storm and lightning flashing in the background? Could there be a dramatic human element involved with this as the background?
I have probably rambled on for way to long but I hope that this will help you to consider possibilities that you might not have thought about.
