Looks definitely like a fish would eat it. What’s the eye made of? Does the pattern ride hook point up or down?
The trouble I’ve seen with unweighted or lightly weighted Rabbit Zonker patterns is that they tend to float initially. So what can happen is that you see a redfish and take the shot and by the time the fly sinks, the fish has passed by rooting on the bottom and has never seen the fly. And then point down patterns tend to grab whatever is on the bottom, shell, grass, algae. Finally, later on after some casts, rabbit zonker can get pretty water logged and then hard to cast.
My favorite saltwater rabbit zonker pattern is the Avalon Permit fly. It uses two short strips of zonker, rides point up with the dumbbell weight, and makes a clicking noise. It’s pretty compact and easy to cast.
