This one was certainly a bit of a mixed bag. Some differences were immediately obvious, while others were much harder to spot. We had a really tough time with one of them in particular. We're sure you must have instantly noticed the blade in our samurai's right hand, though. In the second picture there is much more shading than what you see in the first.
The shoes are another giveaway. In the first image he looks like he's almost wearing flip flops. In the second one it looks more like a boot (much better for fighting, in our opinion). Next are the swords tucked into his waistband. In the first image you can see the ends of them sticking out past his left hand. In the second image the ends are removed. There's also a line on one of the handles that isn't there in the second picture.
