Go to The Gallery and to The Exchange. Look at some pictures of knives to get an idea of what works and what handle shapes are comfortable.
None of those drawings will make a good knife.
My advice to all new makers is to try and make a perfect drop point hunter. It won't be perfect, probably, but it will be a good knife if you start with a well recognized and tested shape.
If you notice the threads where a new maker posts his first knife and he "knocks it out of the park"....it is almost always a drop point hunter.
