Good news is it works
bad news
I lost some colors
its gigantic
its not im my hand
Well, various things. First off, to fix the scaling, size down the model in Blender or Milkshape or whatever. To fix the hand issue, move the mountpoint to adjust. If you don't have a mountpoint, follow the tutorial and add one. As far as the colors go, you probably didn't apply materials correctly or something. Honestly, I'm not a modeler so I can't help you with that one.
