Gerardo Quiroz is a pixel artist, that's pretty much it as he describes himself on his Behance profile, however that it’s pretty much it is quite amazing. Plus what’s also amazing is that the tools used for these projects below were created Photoshop CS5 extended. I don’t even know which version is that anymore which reinforces my theory that tools are just tools and the important thing is to have the ideas and the skills to translate them into pixel art. That is what Gerard did magnificently well. Take a look.
