i don't like the header (the left--i don't like the font (especially the graffiti font) there, and it doesn't mesh very well). maybe remove the white line and center the text on the right. the gradient is very drastic. maybe try a dark, dark gray instead of the black or move to a lighter gray at the bottom. maybe try to enclose the header. i think you have something there if you add a little bit of structure to it and tweak the design
on the right, i'd remove the destinationx in black. move the gray destination x closer to the picture. maybe cut off a little bit of the gray destination x under the picture. the cutting on the picture isn't very good, but it's only a problem if you look at it closely
that being said, the colors run together nicely, and for its purpose, it's very clean. it's not painful to look at it which will probably serve your audience well (considering the reason that most people will navigate to the page)
the interface is simple, and the website isn't a pain in the ass to navigate through. i think you did a very good job there, but i was never really into coding
