To create creatures in 3D modeling design packages always makes me so exciting. With the super cool features like Dynamesh in Zbrush, modeling just become so fascinating and enjoyable.
I started to learn 3D modeling in Maya,2009.
Now i am still learning modeling skills.
I like to start modeling in Zbrush, whatever use ZSphere or Dynamesh, and then make a low poly mesh or an animation ready mesh in TopoGun. Baking some maps for using in Maya. Giving cool looking lights and render in Vray or MentalRay in Maya also.
Moreover, I also can do some rigging, animation and compositing.
