Very nice photographs.

Nice, very nice.
3 and 5 looks just a bit over-saturated but could be my monitor.
Nice set Otavio. #3 is my favourite, lovely reflections. It does look a little over-saturated to me too though (hope I'm not being too "picky").

Based on my post processing, I am in no position to critique. #5 really does it for me.
Fantastic shots Otavio!
Bravo!
