The color choices really work for me... but I can't really say why.
This is brilliantly done, very nice use of the given palette!! Awesome.
I love how it seems to be a negative coloring yet reads normal too. Awesome, awesome job with the palette.
Lovely!
Perspective nitpick: the shadows at far left and right should fan out more.
Good work but this time I think the contrast is making it hard for me to focus on it.
Either that or sleeping at 3am and waking up at 9am is not a good idea.
fantastic use of the palette!!!
