Alignment: This may seem overly simple but, aligning content makes your designs look more organized. Largely, alignment comes down to making sure that your text and graphics are left aligned (because we read from left to right). Alignment also includes cross alignment, which means that you ensure that multiple paragraphs or images across your design align with each other.
Contrast: This is a crucial concept! Having contrast in your designs ensures that something on the page really pops. Contrast can be found by bringing in a bright color, a bold section of text, or a contradictory theme/concept that stands out from the crowd – there are other ways to provide contrast but off the top of my head these are the three most accessible features of contrast.
Color Palate: Picking the right colors to go with your work is VERY important. The wrong colors can make your designs look cheesy and inappropriate. Personally, I will never forget when I went to a funeral and wore the wrong brightly colored clothes. Colors matter in society, and they matter in design work too! However, picking a good color palate has never been easier. I advise that you use Kuler by Adobe and just use the off-the-shelf selections that look good together. Here is the link to Adobe Kuler:
