Hmm as from my side , I've been into doing skinning for quite some time, I also learned polyflow as well as some modelling. Let's see ,
If that picture is correct , then there is no doubt it's a rip , and also from previous experiences with Erics models, I can't really say it's not correct .
Eric, I already saw that you copied / ripped the previous model, please post a wireframe with no edits . Front , side, back . of the entire arm and hand . If you really did copy this one too , I don't think anyone except newcommers and retards will pay you any respect .
