Like Sean S, I think the overall look (considering your theme) works. He brought up good points. For myself, the contrast of the white borders and font against the black background makes reading difficult. There's an eye fatigue factor with such a strong contrast.
The trick here is to create a balance between the two extremes. Experiment with similar hues and shades. Your header uses a color something close to midnight blue which blends nicely with the black and teal. Consider that as a third-main color.
