Voting was a bit tough, but because some strong contenders "cheated" by having hires pixels in parts (or the whole picture) i ended up with four, so i only had to eliminate one....

I really loved the isometric street-scene with the cars, but unfortunately it does use hires for the sprites....

Shame on Ptoing for not pointing it out more clearly that c64 4-color/Multicolor mode actually has double-wide pixels and is 160x200, not 320x200!

Oh, whatever happened to the LBpixels pic? That looked really promising (Although at least the WIP still had some Hires!)

 some comments/additions about the ptoing facts about the c64 palette:

1) you shouldn't use colorramps that have both green/pink and med. grey/lt. blue. they're too similar in brightness. It looks best when you only have one color of these four. this is also the reason why med. grey is the most potent color, like ptoing says, since you can replace the other three colors when you need to!

2) you can mix the colorpairs linewise, and on a real monitor (or with PAL emu) they blend into one single color, e.g. blue and brown become a very dark grey.

3) The differences in brightness of the color pairs look linear on first glance, but they're not. the darkest six colors f.ex. (brown/blue, dark grey/red and orange/purple) are very close in luma, but the next brightest colorpair (med. grey/lt. blue) is a much bigger jump. There's also a rather big jump from pink/green to lt. grey/cyan!
