A few suggestions

Please, note some of the following issues for you future plugin development:

– Keep up to semantic code. You insert your badges as <h3> elements, which they are not. Use <span> or <div>, not headings.

– Don’t use fonts you don’t provide. E.g. I don’t have ‘Helvetiva Neue’ on my laptop, which makes font: … ‘Helvetica Neue’ in your style.css a useless line of code.
