Just a heads up to all. If you are using 2.78, @8:25-ish Kent selects Dyntopo and then enables a box called "Collapse Short Edges." This is not available in 2.78. You may think selecting "Collapse Edges" is the right choice because it sounds closer, but it isn't. You have to select "Subdivide Collapse" in the dropdown menu underneath the Detail Size bar. This is what will work with the Snake Hook Brush to pull out the head of the bird, etc. So, 1. Enable Dyntopo, 2. Select detail size of 30.00% . 3. Choose "Subdivide Collapse." 4. Choose Snake Hook Brush. 5. Enable WireFrame. 6. Make radius of brush a little smaller than the size of bird's head. 7. Start pulling and shaping. 8. Smile because you got it working! :) Hope this helps some
