I'm finding it difficult to say anything, without being insulting, and I apologies because clearly you are young.
I spent years in product design and this would have been rejected even as a sketch.
The product looks like an idea trying to find a problem, and even if this problem existed for most people (which it doesn't) the design is over-the-top. Any product like this should look and function as if it wasn't there, so that it seems natural for the user, that it should be an extension of the device and of the person, not a bulky add-on. It should feel like once you have used it you wonder how you lived without it. But please don't waste any more time on this idea, it's not solving a widely recognised problem.
In your designs think about refining every aspect of it until it looks good on paper before you commit to a model or prototype. Think in 3D.
