Knife looks awesome, darn near perfect as far as I can tell; clean lines, great fit and finish, design "works" aesthetically (i.e., proportions, curvature, etc. not out of whack and looks very functional). The only thing I notices was maybe you could move the thong hole back a tiny bit, like an 1/8" so, just so that if there's a lanyard in it, it's interference w/ the user's grip is minimized.
Re: sheath. That looks good too. The stitch spacing/uniformity maybe could be improved, but I only say that because it's something I notice with my own sheaths and your stitches are still much better than mine. A leather edge beveler might help with the upcurled edge look, which at least with my sheaths seems to result from how I use the belt sander on the edges. I still haven't figured out how to stop it from happening. Last thing: I noticed your rivet looks like one of those Tandy double cap rivets, and that the post may not have upset properly. I quit using those b/c I could hardly ever get them to upset properly, and even when I did it felt like I could probably pull them apart w/o too much effort. Plus you'd sometimes get that bump where it looks like the post is trying to pop through, which I didn't really like.
Beautiful work, I'd be proud to take it into the woods. Thanks for posting!
