It's hard to see much detail in the photos. Honestly, your photo skills suck ALMOST as bad as mine! (I've pulled up old photos and thought, "Wow! That's really terrible - oh, wait, I did that!) Terrible background, too. But, of course, you weren't looking for photographic comments.
The sheath goes well with the knife. I don't know that I like the way the belt loop is set up, but that's just me. The stitching could use some "love". You put a lot of stamp patterns on the sheath, but they don't all go together and it kinda becomes like random noise. I'd rather see it kept simple, or kept minimal.
I don't want to be too critical because it's really hard to tell much about details in these photos. Like I say, the style does go well with that knife and it's not bad. I always have great respect for a person that sincerely wants to have his work reviewed because he wants to continue to improve. Nobody can do that looking at their own work; you will see certain flaws that may mean nothing to a customer, but miss things that would really improve the quality.
