Sorry dude i dont understand your language
and one thing why there is .br after .com
The websites look nice, although I don't speak Portuguese (I assume that that's the language you were using) so I couldn't understand a lot of it. I was able to understand about half of it (I can understand the words that are spelled similarly to Spanish words).
It's a brazillian domain I guess.
The second one looks best in my opinion. I really like the colors.
The third one with the random renders could use some type of blending to put everything together less awkwardly.
I'm getting an error message for all sites
