Tommy Wong is the first place winner of the Mixamo Space Battle contest. We were simply amazed at the overall presentation, creation and look of the character. His skills in Blender are amazing so we decided to take some time and ask him a few questions and let people in on his secrets.
Mixamo: Can you tell us about yourself?
Tommy Wong: Hi there, my name is Tommy Wong, or Yung as I’m known in a few forums. I live in Kuala Lumpur, Malaysia where the weather is either raining, hot and humid or VERY HOT. I’ve been dabbling in 3D for 5 years or so now, and I focus mainly on character art, organic or hard-surface. Before going full time freelance, I’ve previously taught 3D modeling classes and I’ve also worked in numerous local 3D animation houses as a 3D generalist.
I am also an avid gamer and toy collector, and if you want my money, just throw in cool robots and I’ll open up my bank account for you! I am currently studying as much as I can about game design and game development, and I hope to start developing my own mech games soon.
