It looks really nice!
But: The tang might be a bit to wide, the amount of wood seems to be quite small on the spine side.
If you carve/cut wood, the pressure might split the handle.
If you look on traditional Scandinavian stick tangs, you will see they are much narrower.
I put a wooden handle on a Mora 2000 blade last year, and when I wanted to cut off some cm thick branches from a birch tree, I split the handle at the spine.
I then reduced that part of the tang by about 3mm, did another handle, and it is fine.
I also did two pins going through the handle and tang in the rear end of the handle, thinking it may stop the movement of the tang inside the handle.
Not sure if this makes it stronger though!
