Sorry...I am no photographer, but the sky looked cool tonight over the city

Looks good to me.

Very cool - it's the the picture's a rolled out circle, going from light at the top, through some colors, to a light blue, then a darker blue in the distance, back to light in the foreground...lots of movement...very nice!

That picture almost looks like a winter scene.

Thanks guys..my try at armchair photography.  That is looking from my window northwest toward O'Hare. 

A nice sky indeed!
