Someone pls help me to find out the problem of the design.

Looks glossy However there are so many awesome buttons on the marketplace and I think that it is the main reason

as greedybrown said there are SOOOOOO many buttons that look exactly like yours, that have more detail..urs are a bit simple, along with the bubbles.

Thanks you very much for helping me ! Will the bubbles work ?

I know that the 3D & glossy works but for buttons the details matters a lot.
