Canberra...some HDRs...help needed

I just wanted to get some feedback on some HDRs that I did from my recent trip to Canberra.
I had a bit of a problem with the sun glare in this one (it turned out as a grey blotch) so I have used a control point in Capture NX2 to try to fix it.

This one turned out alright, but I am uncertain about the colours...are they too unnatural?
