Hi Pradyoth,
Again you haven't added description to your images but it is important that you do this because if we are going to write a critique for you then you should at least help us with a description.
Overall I like the image, the arches are very photogenic but unfortunately you have hit on the big problem with shooting in dark areas on a bright sunny day. Your eyes can see at least 16 stops of light and I've heard up to 24 stops of light so your brain has no problems in seeing this scene. We can see bright light and dark shadows without much of a problem. However, your camera can't, it can only see around 8 stops of light which means that it cannot capture the range of tones that are in this scene. Hence the bright overexposed external light and the darker shadows of the arches.
The shot is also not very sharp either and in fact I can't see anything that is sharp in the image and this is probably because of the slow shutter speed and a little bit of movement in your hands.
To be successful in these types of shot you need to use a tripod or put the camera on a stable base, expose for the bright ourtside light and use flash to light the inside. Alternatively you could use exposure bracketing (HDR) which use a minimum of three images to create a wider tonal range by taking 1 shot under exposed for the highlights, 1 shot on correct exposure and 1 shot over exposed for the shadows and then sandwhich them together in PhotoShop or other software like NIK's HDR or Photomatix.
I used exposure bracketing to take this image
HERE so you can see the results that you can create. These arches were just as dark as the ones you took and the external light was very bright.
I've uploaded a very quick mod to show what you can do, I toned down the overexposed areas as best I could in the 2 minutes that I had, raised the shadows added a little colour, used the warp tool to straighten the pillars and sharpened.
Hope this helps
