For comfort and visual, the bulge of the belly needs to be centered in the length of the handle.
The little bit of "guard" you have extending below the edge is a no-go for me. It makes chopping on a cutting board, for example, problematic and doesn't add any security against slipping forward onto the blade. I'd remove it entirely, but if you want to do something nice and get the edge a bit farther away from the leading finger, think about a spanish notch.
Other than that, they are good solid designs and are simple enough that anyone can accomplish them. Too many new makers go for outlandish blade shapes straight out of a comic book and then wonder why they're having problems. Clean, simple, functional.... there's elegance in that.
