Why your mesh so high vertz. but mine is low vertz
I have followed the appropriate steps in the video (from beginning to 9.43). I use Smooth brush too (hold Shift) like the video, I have enabled Dyntopo too. But in the end, my verts is a little.
How can it be like the second photo (the teacher's mesh) that I attached. Which is a lot of verts and much smoother.
btw, my blender version is 2.79.
