Well, kiss... Knowing CLAMP, they'll only get close to a kiss and Mokona'll interrupt them by suddenly bouncing into the screen or something. I still have to see the first CLAMP-kiss (although they got pretty close in some manga). Deep sigh.
But the barrel scene was awesome! I totally loved the movie just because of that. And Syaoran's hair colour wasn't too bad - it suited him in a way. I liked the new outfits, although it wasn't made clear how they got them - it's not their ordinary outfit, so I assume it's an outfit suiting that world.
And about Syaoran's eye - it was such a nice detail! I totally loved it, although I didn't really notice it until it got all dark. I first thought it was 'cause one eye caught more light than the other one, but no - then I realized it's because of his blindness. Nice detail, I think it's better than they grey-tones they use in the manga to show his blindness.
Overall, I loved the movie but it was way too short and therefor rushed. But ah well, we can't have everything.
