Making the earth look real.

[Shponix]

Hey could anyone give me some advice on how to make the earth look real please?



Or just making the picture look better generally. Thanks.

I would add an outer glow to the earth and maybe even out the edges and put a bevel emboss very slight. And what would really look cool is if you make it look like it just dropped into the glass and sinking (rising bubbles and splash) LOL
