Welcome to the board!

You beard coverage and density is absolutely amazing! You already have a great beard

1) great progress, better than average.

2 & 3) doesn't look bad now and it definitely wasn't butchered. I would start immediately carving that area to the shape you previously had it. Don't worry about creeping it down or anything like that, just pretend the accident never happened!

Keep it up man! Post weekly and show us how it's coming along.
