Not bad in the frame work. Have the content proof read, though. English is not your native language, before you let people question your website through contextual imperfections, it's better to have someone read over it and make corrections.
The scrolling test in the sample section needs to be reworked, it cuts off.
The banner in the sample section needs to be centered, it's currently off to the left.
Under contacts, build an online contact form. Not everyone has outlook configured.
Remove the scrolling news from your site, they distract from your message. And in order to present your skills, you NEED a flash section.
Other than that, even though i'm personally not a friend of the orange, it's your color of choice and doesn't interfere with anything.
Generally its a very compact site that needs the proof reading done as the first and most important item, then you should take care of the revisions and enhancements. :tu:
