Hello, it looks like the add on used in the lesson is no longer compatible with blender 2.8, do you know if there's an alternative or a newer version of this add on ?

Greetings! I'm new to sculpting in Blender, and I don't really understand the decision you made in this video to extrat the belt from sculpt mask. 

Wouldn't it be easier to create belt using polygonal modelling from a primitive instead of sculpting it? Looking at the reference image, the belt doesn't look pretty complicated. Wouldn't it be faster and easier to model it first and then sculpt little details if needed?

Whenever I apply a Subdivision Surface modifier to the hat, it rounds out the top of it and I don't get a sharp edge as shown in the video. What should I do?

For flattening the belt edge, is there a reason not to intersect with another flat object to trim the rough edge? Geometry complications perhaps? Thanks!
