It's really nice Artico, I was expecting a fully decked out portfolio site from the topic title but at least you made it somewhat clear with the
bold, red post script that it's just a splash at the moment.
I actually love the non-grunge version with a solid background much more than what you have on the site at the moment. If you're going to grungify it, I'd knock out some of the shapes rather than just add a grunge brush stroke on top of the design. My only minor gripe is that it doesn't actually
tell me what this site is! Sure you have your name, "my portfolio" and a contact area but it doesn't tell me if you're a graphic designer, web designer, both, neither... you get the idea. Just a couple words under your name inside the white 45 degree bar would solve that. Finally, it's a pet peeve of mine so don't listen if you don't want to but, can you take out the full-stops (periods) after the text?
As you can see, only minor comments on a really nice piece of work.
