I actually really like the design and color scheme, who cares if it looks kinda like sitepoint here is my big critique:
Hope you don't mind I circled the issues I found and hosted the image on my hosting, let me know if you want me to remove it or send you the file.
Make sure all of your sections/content groups are equidistant that means set up a base distance or two that you use to pad your elements, try not to use more than two, and make sure the elements are the same in terms of relationships, so banners are always the same distance from a content element etc.
Looks good though good job.
