Thank you very much pony that was a cool comment Pony
As you just said I am not into too much of texturing but I love this field and I want to master it ..although I have seen many tutorials regarding this matter I still feel I am not able to make the picture which come into my mind

About the settings and rendering engine I used .. I used the Mental ray engine for rendering both the images
Both the first scene was rendered with out any lights I used the global illumination (GI accuracy 100 and GI size 150) and the final gather with (100 rays mind photon radius 15 and max photon radius 150).
The second one was rendered using the mentalray as well but with an ambient light with 0.5 intensity value.
Both scenes were surrounded with a poly sphere textured by HDRI tiff files.

And I don’t know whether these setting are the best for rendering or not I just felt the image look good.
But your advice was cool Pony and I will concentrate on texturing part more

Looking forward for more opinion and advices
Thank you very much in advance
