The basic shape is a very nice knife.
I agree with Fletch that you should move the scales back so the bottom comes right to the bend of the finger groove. Don't leave that tit sticking down or it will break off.
I would not move the plunge as forward as much as he did if you move the scales back. With the room created by the scales being dropped back, the ricasso should be OK where you have the plunge.
I would leave a little swell in the bottom of the handle, but not as much as you have. Somewhere between Fletch's line and yours.
