Just fixed it, I think it was a good move, looks a lot better.
Thanks but I meant for the sky to be like that but I will add some AA, thank you for the feedback.
I like the colours and style here, but maybe some more traditional pattern dithering like shown here: PJTUT might make the gradients int he sky smoother? I also think a little aa on the edges of the black would be good too c:
Nice one!
