I like raw (imperfect) additions to some items. Your sheath for example, I would leave alone. Part of the allure for me anyways is having something I made and I like the home made looking items. I really don't want my stuff to look like I went to Dooney and Burke or whatever and just bought them. I think you did well.
BTW... if that is a knife you forged, you are certainly better with fire and hammer than I am! Good job all around!
