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:
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.
