I am not a maker, I am however pretty picky.
I really like the shape at the heel for the most part. The near square transition from the bottom of the tang to the verticals at the back of the heel looks good. The heel itself needs work. You are missing a facet on the lower tang that allows the blade to sit lower in the scales. It is the little triangle at the front, bottom of the tang. With out it the blade won't sit right in traditional scales. I like the taper on the tang down to the tail. The tails look like they are the right size for the blade. I have no idea what happened to the nose on those blades. They all looks not quite right and I can't put my finger on it. This is mostly completely subjective comments though. Most of what I have said is about design aesthetics and will vary from person to person. I was just scrolling back and forth and the one with the Spanish point may have the triangle facets. It does not show in the other group shot though. It is a seriously technical skill set to learn. It looks like your grinding is getting closer.
