Perfect resume. The headlines are clear and can be read at a glance.

Your font should be limited to three sized and three styles, no more. Ideally, you should be using simple, yet professional looking fonts like Helvetica or Sans Seriff, your fonts should only be limited to two colors at the most, and font style changes should be limited to italics and bold text. It's always nice to have an attractive resume, but you should do this with your words and claims, not with a dizzying array of font sizes and colors. You should always let your words take center stage.
