It honestly looks cool because it’s different if that makes sense. I don’t think anybody else would see it like you do. We are our toughest critics with insecurities.
So you have groups of 4 knuckles? Thats actually pretty cool. Almost like having the ring and middle finger glued together, wouldnt expect that to be too different (though i am curious 🤔). If you wanted, im sure you could get (or build) some cool prosthetic that is close to having 5 independent fingers.
