I took a look at your website and I would say you definitely need a new logo, you were saying you wanted something more graffiti/street art like. I already have an Idea for a simple logo, which I would create with actual spray paint, after that I would scan it in and send it to you.
Next to a new logo you need a new look for the buttons in the header, they're not really eye-catching, I also have an Idea for that, but to make everything look great when it is set together you should use a black and white stone wall as a background. With the black and white wall as a background, the logo I have in mind, and the new button desing, the website's desing is almost completely in black white and gray, which gives it the look of an graffiti and street-art oriented, sub-urban artistic look.
