The more that I look at your knife's handle the more I'm glad that I'm not working with it. As Geoff said, that design will put some blisters on your hand. The guard and pommel also have points that serve no purpose and could make the knife irritating to use. I would also recommend that you round the point of the blade. If you want it to be primarily a chopper you could have a more obtuse point but if you want the point to penetrate it's going to need to be more acute. You asked for my opinion but what you have sketched out on paper strikes me as a zombie killer rather than a functional knife.
