Kier's latest venture is creating digital contents for social media. He uses Adobe Photoshop and Illustrator to create freehand digital cartoon employing his own style of color selection and shading technique. For added humor, he inserts Filipino puns and quotes, which reflects his fun and outgoing personality.

In the past, Kier has made logos and posters for organizations and events. His designs are clean and simple, but has a strong emphasis on the details that are essential to the concept. He believes that feedback is important for concept and design improvement.

Inspired by the technical aspect of portrait painting, Kier started experimenting on painting human subjects in 2013. In the beginning, he used color pencils on paper as his media, but as his dexterity improves, he experimented on watercolors. Today, he finds comfort with working on watercolors and is open in exploring other media.
