Tip: There are only four icons - I would expect them to be embedded in the README (or whatever different landing page you chose for this post) because as it currently stands, your link points to nothing of value and one must hunt through the repo to find the icons (individually).
You may want to consider contributing to the MoreWaita (<a href="https://github.com/somepaulo/MoreWaita">https://github.com/somepaulo/MoreWaita</a>) theme.
