The overall design is good. The curves really give this site some character. I think you did a good job incorporating some of the header elements into the footer as well. The icons are also a nice touch. There are just a few points to consider for improving this design:
Scatter the pictures into the gray area of the header to fill in some of that empty space. As it is, there are too many pictures crammed into a small area and the bottom of these pictures sit too close to the right column. Moving some into the gray area will not only fill the gray space, but give the right column some more breathing room. Also, consider decreasing the size of the stroke around these pictures.
I'm not sure that is the best place for the navigation. It may look better to place them in the top of the white curve, just below the current position. The angles make the nav too playful and hidden for the audience.
Finally, consider a different font for the website title. This type doesn't seem to fit the purpose of the site. Try something more professional.
overal this design must have a content to anticipate the empty space. More fun with color, not only stay on one or two colors. Keep going Chris. :)

probably your color is need saturation color, which is if you make a blue on major of your tone manner, so the brown color is not the right color, it can be white or blue milk or yellow or orange etc
the black color in the outline is too dark, find another color can bright and standout the logo
nice grid.
