As is tradition, every member of the Whisperwind family receives a musical instrument at a young age. They are taught how to play it, maintain it and above all, cherish it. Although this cello currently belongs to Tyrande Whisperwind, it is often played by her wisp relatives while it is stored away.
I use Photoshop to sketch out my design, model it in Maya, export it to 3DCoat and back to Photoshop. There's different programs you can use though, for example Blender is also a great alternative to Maya for 3D modeling. If you're new to 3D programs I would experiment with Blender first.
