I just finished my project.
I do like your design for larger width screens. I am curious why you did not try to keep the same look even at smaller width screen sizes? Also, you might want to look at changing the media query which transitions to the next smaller size screen, because before you make the switch to the full width design, the layout is wider than the screen, so the horizontal scroll bar appears (see below).
Thanks for the info: I fixed the scroll bar issue.
