A few things I picked up on immediately; 1)You might want to add split rings between the screw-eyes and the hooks to reduce the ability of the fish to throw the plug. 2) Taper the tail and it will have a better profile and probably swim better. 3) A thicker bill won't be as prone to snapping off when you run it into a barely submerged boulder(HINT) 4)A coating of 2-ton Devcon epoxy is cheap (>$3) and will help it last a lot longer and if you put some on the screw-eyes threads and screw them back in they'll be much stronger.
Tight lines,
Wade
