Mario RPG: Legend of the Seven Stars has taught me well; that's not a Treasure Chest, but a Pandorite! Nice try!

I like this(/these) piece(s), especially the Mushrooms. Most isometric pieces have a hard time convincing me of depth and sphericality — I'm pretty sure that's a word — but you've done it quite well. I've only a few complaints:

• The dithering is kind of rough. There's a little bit too much contrast between colors in the palette. When dithering, that can make the piece look very grainy and rough.
• The dithering on the Mushroom spots make them look like they're protuberous. I've always imagined they weren't but color differences, but maybe they're actually supposed to be protrusions? I've never really analyzed it.

Overall, I like the piece. There's room for improvement (but isn't there always?), but taking a full 1/5 off off the score seems a bit steep; and since I can't yet vote 5/6, enjoy your 5/5.
