Re: review my site
Befor ei start let me make it clear that my criticism hopefully will help you.
Its ok, if it were not for the fact you were advertising services as a web designer it could pass. Think the fact you used tables, everythin looks very square. Also one of the sites in your portfolio is basically identical to your own site.
One point on the images, particularly the one on the portuguese site in portfolio, its way too big, resize the smaller one on the homepage and let the big one load if a user clicks on it.
A word of advice would also be too fill your portfolio with varied sites. Not so much a portfolio but a gallery of what you can do. The web is full of people who make sites now, and chances are a customer will have a quick look around lots of them, you will only get one chance to impress them so a good portfolio or showcase is a nessesity.
Hope you dont think I have been to hard.
Wish you well with your endeavours.
