I like this model.
It's very high poly, the wrap is messy but it is ifxable if the author tries hard.
I fixed some stuff for you, kevlon999, if you don't mind.
I have fixed the walk animation, the wrap-problem and an apparent crash ingame.
the keyframe
made the model crash (I think)
The walk animation bug was caused by some bad keyframes (scale)
you just scaled the model down a lot in the middle of the animation.
The wrap bug was caused by a bad texture; A texture size should always be 32², 64², 128², 256², 512² ....
yours wasn't even a square.
The high filesize was caused by a portrait that was the same as the model itself. I added a camera to the original model so a portrait shows up ingame.
You still have to reduce the polycount a lot!
here is the fixed model and texture.
