You have a good beard coming in there. Don't be too self-critical. You may focus on the thin spots but others see a fine beard coming together. And as has been pointed out, the patches will likely be filled in the coming months.

Mark

How good and pleasant it is when brothers dwell in unity! It is like the precious oil on the head, running down on the beard, on the beard of Aaron, running down on the collar of his robes!  Psalm 133:1-2
