It's cool how the colors look vivid, but yes the outlines are really strong, how can clouds have outlines so strong...

Nope, just a randomly chosen palette

Are these game boy colors?

Thanks guys, was experimenting with a different style. Probably could have eased back on the outline a little, especially on the leaves, but was fun to try.

Congratulations, you have my vote. The colours are perfect, don't change 'em!

If you're going for a washed-out background, the gray outlines aren't working too well. I honestly don't think outlines for the clouds are needed at all. Very nice saturation, though, and I mistook this palette for the DB16 briefly ;)

Cool colors, the high saturated look is nice :)

I like it.
