The exposure on your first picture seems about spot on. Unfortunatly, youve increased the exposure on the subsequent shots. Once you've burnt out your highlights, you've lost them for good. It's a lot easier to lighten parts that are too dark. Having said that I've had a go. I don't know how far you want to go down the Photoshop route, but you may want to consider combining 2 photos to get the result you want. I've just joined this group, so I hope I'm doing this right.
