I think your best work is still the first Hero and the original reward. They're both great, but first Hero was the most emotionally invested for me. It's always interesting to see more of the same characters, and these two specifically, though Wilhelm didn't really have the personality I thought he did in the first movie. He seemed like a stern toughguy, and maybe the progression is just him growing up after making a goofy friend, but I never thought he'd grow and keep that big mustache. That's just my perception anyway.
I hope your kickstarter makes it, I don't have any money to donate atm. Hopefully people join in at the last minute since you're about halfway there.
