I think you have an idea that will catch fish. If you had a black back and gray body, or gray back and white body, it would be a natural color for that tie. Bucktail and kiptail would also work, but the craft hair that you used will have lots more action. Good job. The dumbbell eyes I have are in a couple of sizes, and some of them are just plain huge. Salt water I guess. They’re fun to fool with so enjoy yourself, no telling where the idea will go.
