Obviously, the right side of the image is way over exposed. Even the left side of the image could afford to lose a stop or more. You are starting to get keystoning at the top of the image, where the vertical lines of the building start to skew inward. If using a 4x5 camera, set the tilts and swings so that this is corrected. If you are using a digital camer, this can be corrected in PS. Use perspective, or skew, to make the verticals straight. You might want to try another angle. Taking a photo from this angle, people often like to see symmetry. If you went to the right, through the columnade, and shot through the columns to get the archway, that might make for a better composition. With digital, practice 'seeing' the image. Take as many images as you can to try and train your eye to see compositions. The place is beautiful, now you just have to capture that beauty in your image.
