I'm really struggling with the shading of the trophies.

This out of the 3 versions of trophy I think might be the closest to being good.

But I'm not sure how to finish the shading. How would I shade the handles or the bottom? I would love to know if you think what shading I have on it is done correctly. The method I used was just to copy the object and add one gradient that goes from black to transparent, then just adjusted the alpha. I then added another layer and did the same thing with a white gradient to add some light.
The second trophy has more of a cartoon look. And I do like this, but I'm not sure where else to add black shapes to represent the shadows.

Any tips would be greatly appreciated. Thanks.
