Welcome and your English is fine.

You want to use scattering for your atmosphere.

Besides using an image map. You can add a normal map to give some depth 
and a spectacular map for the seas. You can find some here

The atmosphere is always tricky to do and I generally cheat and use a 
cone behind the planet in line with the camera.
