I think they're fine knives. But you came here looking for constructive criticism, so I'll dish it out:
The handle/guard/blade transition on the bowie is a little odd looking. Sort of "not well resolved" and pinched looking. If you were to look at just the blade, would you expect to see that handle sticking to it? There's no "flow". Still, it is a fine knife I'd love to own.
Of the two hunters, the one on the bottom is a bit strangely proportioned and the guard is kind of clunky next to the small blade. The four materials you chose to sit next to each other aren't "talking the same language" as cohesively as they could. They don't clash, but they're not working with each other either.
I think the knife on the top looks really good.
Sometimes when I'm designing something, it helps to pause for a while and come back to it fresh. It is difficult to look at something objectively without fresh eyes. Look at these knives a year from now and I'll bet they look different to you.
Anyway, these are great knives. Thanks for posting.
