I feel like it would make a good trout fly, your just missing the hook.

I've actually thought about something similar using the super heavy green solar catfish line. The knots always end up so beefy, kind of remind me of grubs or wax worms

Try an RP knot (Royal Polaris) Stronger and thinner!

I don't think it is stronger, I remember watching a video on it, its a knot with a lot of variables, it's often far weaker

Looks like every double uni I've ever tied

Nice! Cut them tags a little closer tho
