Being very subjective, I would shorten the height to 47~48 mm and make it flatter a greater part of the edge to a gentler curve upwards to the tip, no changes to the spine or its drop. Having said this, it looks great they way you designed it
The angle of the tang relative to the cutting edge looks spot on to me. Not kicked up too high like some. Still, an extra 2-3mm in blade height at heel would balance the wrist angle a little better.
