It's not really a 'right' or 'wrong' thing. It's just an aesthetics thing and that is highly subjective.
All I meant is that the plunge line is angled forward, meaning it's not perpendicular to(or square to) the spine. Instead, the top of the plunge line (meaning the end toward the spine) is tipped forward towards the tip of the knife. Which isn't necessarily wrong. It just is really accentuated by the angle between the handle and blade.
Now, for that sharp angle between handle and blade....personally I don't care for that at all. To my eye, it really disrupts the flow of the knife.
As for the hamon....the majority of it is maybe a *tad* low, but you don't want it a whole lot higher. But the part where it drops off the edge is an issue you'll want to steer clear of in the future.
The ricasso is a pretty big heat sink. It robs the heel/choil of your edge of the heat needed to harden. If you used clay to do your hamon, I would suspect that you used too much clay (and possibly too much heat) and the larger, thicker ricasso robbed the heat from your edge at the heel.
