Design Reflection for business cards

I've designed a perspective view in which i show off my business card design. To make it realistic I want to use lightning conditions effectively.

In some Cards I they use beautiful frosted glossy reflections. here I'm giving you a link of an image. You will then understand what I need to know.

I need perfect visual appeal to my cards' design.

Answer

Instead of using a gradient as a layer, use a layer mask with a distorted border.

Create a layer mask

Blur the edges

Distort the mask

Adjust layer opacity and blending. By using the 'Blend If...' Feature, you can knock out the edges of the card easily.

Clean up your mask edges, and adjust your lighting layer's colors
