What will you use the knife for? that will really define much of the shape as a base starting point.
Understanding the balance of weight between the blade / handle / and tang will be important. You may also want the neck of the tang to be thicker as it leads into the handle.
one last thing - i see the the through pins in the front but i think if you are doing the layered you will also need a through pin at the back. Keeping in mind that the layered design will mean hand washing vs machine washing. but when you have a quality knife you treat it with love.
