Clean use of HTML5 and a nice simple structure. The only main issue is the use of an aside element to enclose what is essentially the main content of each section. An aside is for information that is in addition to the main content and wouldn’t detract from it were it not there. Simply removing the aside here would be fine. Also, remember that the type attribute is not required in script and stylesheet link elements.
