Social Share Buttons for Jornal Público

I needed to standardize the social share buttons for http://publico.pt pages. I recreated the basic share buttons provided from both facebook and twitter and tweaked them to make them more consistent when presented together.
The top, bigger, ones are for a news piece page - for a 145px column.
The smaller are for other pages and iniciatives where sharing is required - they will usually display along the header.

What do you think?
