The loser's bracket entries should be rotated based on which round they go out in, so I don't end up with this:

Round 1 of loser's is fine, but winner of 133 should go to 139 and winner of 135 should go to 137. (And the same for the subsequent matches.) If you flipped that, my loser's round 2 would be Sonic vs Mega Man, Samus vs Crono, Pikachu vs Sans and Kirby vs Sephiroth. As it is, we have 3 repeat matches and would have had 4 if I hadn't taken Seph > Samus.
I'm hardly saying these are the correct picks, but for demonstration purposes, it works just fine.
