They look pretty good. :thumbup:
For what it's worth, I find it easier to re-sheath the knife (while you're wearing it) if you run the back piece up a bit higher than the front. Then you have a surface to glide the tip along to get it into the sheath.
Also, when you are folding over a single sheet of Kydex for the sheath, it may not be necessary to add a drain hole. You usually end up with a bit of a tunnel were the fold is, so water can just run through it. Otherwise, a drain hole on the back side would be more aesthetically pleasing (although it may dump water on your clothes).
