Can someone help me make a translucent overlay

I used a background eraser but the middle is still apparent and not clear as I’d like it to be. If I change the opacity the brown color is still there, I want it to be clear all around and shiny. I hope that makes sense. Could someone show me or help make one for me?

u can try at
or if that doesnt work then try finding a better picture; a clipart, any png or any picture where the background color is a one solid color
if u find it go to the page i mentioned
