The sun has a light source affecting it :( . You've shaded it like an orb, which it is, but the sun is an orb of fiery gas so bright that it appears to us more like a disk.  I like the buildings, however.

Thanks for the comment!      

It seems like the ball is near to us.

The colours you have chosen and the contrast of the sun tell us that the ball is the nearest of all. isnt it?

nice coluors!

What we did with the sun, was a purpose, because the image is of global warming, I thought it would be good if the sun was seen as a source of heat .. and not as a light source. Because of this color is orange sun ..
In addition to the polluted atmosphere.
Thank you very much everybody for your comments!

it's interesting I like it alot but I Was thinking just what they were thinking. The sun, our main source of light, has a highlight in it??? LOL! Cute.

Well done, but I must agree with the orange/sun critic.

But I still love it, well done

I like this picture!

or we're actually looking back at earth from our homes on the planet Bradbury.

i like the shifting in this, but yeah, the sun ends up looking more like a flat disk because it's a ball of fire.

but what if that is actually a small orange which just happens to be in the air at that specific spot?but if it's NOT an orange, then i really think u should change it too : /

yeah considering the sun is a source of light you shouldnt really add shading to it

Erm, I've never seen the Sun have a highlight like that.
It is lit by itself, so it cannot possibly have a highlight in top left or anything.
