Hey Joao,
I think it looks good! Here are some changes that I think would make it better
-Turn off the auto play audio. Its nice to have some music while you scroll but a lot of people find auto play annoying.
-Background a little darker or grayish would look nice.
-If you could compile a short reel (1:30 min or less) of various projects that you are proud of and have that on your home page that will be a quick introduction to you. I think that works best.
-I don't think the home page should be a blog. I think it should just have some info about you and what you do with a short teaser reel of your work (my opinion)
-When you click on Bio the actual bio text is under the music player and you have to scroll down to see it. It should be seen up higher as soon as the page loads. Maybe switch the music widget below on that page.
-If some of your credits on the credits page were links to media or those projects that would be nice for people looking to learn more.
-I think you recommendations page is really cool. But try to have someone help you get the text to the right of the picture so the page is smaller. I have had that problem too sometimes on a site it's so annoying to try to get the text in the right place.
-Your contact page is nice and simple. If you wanted to you could also combine your Bio and Contact page and just have a short bio about yourself above you contact info.
Otherwise it looks pretty good!
