The characters and overall animation/artstyle look like they come from
MMD. Additionally, the voice acting seems... american I guess? Idk but it feels like Japanese voices have a lot more emotion to them and RWBY seems to lack that. What's going to make or break the anime, in my opinion, is whether or not the story is interesting. Right now all I see is BOOM BAM EXPLODING FISTS ICE BEAM NINJA CUTTING SKILLS but no explanation for how or why. Fingers crossed it turns out good.
