A simple, quick, and effective tube fly that always gets the first soak when I'm out swinging for winter fish. They can see it. It's easy to cast. Moves great. Sinks well.
From what I could make out the fly looks nice but this is nearly impossible to watch with the focus being so bad and your choice of white t shirt creating zero contrast between the foreground and background. Next time try using a smaller aperture (larger F number) on the lens so you and the vice are in focus.
