Beautiful shading on the clouds... this is why I stuck with 3 colors for mine.
Agree with crits: both clouds and city look great but don't fit each other.
The sky bg is probably too dark and / or desaturated; the light source on the clouds isn't consistent with it.
You know this, of course...
the palette is very dramatic. The buildings could be darker or at least there could've been darker buildings in the back.
Beautiful foreground clouds, the big flat dark area at the back is a bit out of place though and the city doesn't blend well in the scene with its cartoony outline. Those clouds are fantastically pixelled though
Love the clouds, but don't like the rest. The city seems so out of place!
Those clouds have a great outlandish feeling. But the city is a bit cartoonish in comparison. In the background sky there's a color (#2) that look odd coz it's brighter than its neighbours. The darkest part of the background could use some smoothing or be brighter. Still, nice piece! :)
All of it's fantastic. I like all of the colors...except the brown in the sky. The brown in other places works fine, but the brown against the purple is kind of bleh to me. That said, I am completely biased and the color brown is by far my least favorite.
I wonder if the buildings could use a softer outline. I think I'd like it either way.
