it was supposed to be 240x160, not 160x240, which might cause some hassle later on )
alluding to the final challenge, perhaps?!
Snake, love your entry, though, some parts seem a tad sketchy, but i guess that is expected when pixelling a sky, something that isn't really structured or defined, as well as with limited colors. A great job overall. I kinda wished the lightening was more contrasted, but it looks nice.
Mirre, I like the layout of yours, a nice vertical panoramic, but i can't help but feel that the 50% dither throughout most of the lower portion could have been mixed up a little, with different patterns to add more interest. The moon is nicely done, and it flows well as a whole. Good work.
