It looks interesting, and there's only one way to find out.? Either way, you're bound to learn from it. Just try to make sure that the weight is dead center, as well as the line tie and hook hangers. It's fun to tweak your own designs into a functional bait, but it can take time.
I'm always sketching and designing new stuff I haven't made before. Some of them never get off the launching pad, and others do well enough on the first attempt to keep playing with. Here is one of my sketches that I'm working on now. It's a 3 piece jointed Muskie with fins and tail. It will be interesting to see how the prototype swims and getting the weighting figured out. All I know is that the finished product looks really cool in my head which is a great way to start.
