    Here's the link to my showreel: https://vimeo.com/84025409 Password: just a reel And here's a link to my short written works: http://phosphenelights.wordpress.com http://shortstoriesofjoy.wordpress.com As a graduate from an Arts College majoring in Animation, I take pride and passion in creating works of art that would create an impact on the viewer or the client. With a few years of freelancing and year of experience as a Motion Graphics Artist in a post-production company, I have gained many skills in terms of design, software capabilities (Adobe Photoshop, Illustrator, InDesign, Flash, After Effects), as well as communication. I work well with clients and am able to handle the whole process of a project, from pre to post production. Also with a background in literature studies, I have an excellent command of the English language, and have created and written a few short stories and written works over the past few years. This good command of the English language has also enabled me to work and communicate well with clients. When given a task and a deadline, I will be sure to carry it out from start to finish. As a perfectionist, I would always be sure to take note of small details that would ultimately affect the big picture.  less
