Loved Versailles, didn't so much love Paris while I was there. Or maybe it was because Paris didn't love me. Either way I didn't get to see the gardens at Versailles because there was a concert there that day and it was 15 or 20 euro to get in. I politely took my shots from the upstairs windows and called it good.
I agree on the first photo, you have conflicting subjects because of the colors, though the DOF makes it pretty clear what your intention was. Your stop time is perfect though. Am I jealous of the stop time, maybe a little.
The second photo I have trouble with because of the shadow captured on the statue above the shoulders. You lose a little something there IMO. Secondly, I agree there is too much water in front of it. Maybe decrease your DOF to only the statue and give a bit longer exposure if possible, that might clear things up.
I like the third shot, it has a little shadow in it but nothing distracting. I know how hard it can be with those fountains and shadows, even my fill flash on the d70 can't clear it up at times.
