why are the 6 hours wasted if he made this model to find out what advantages blender has over med? ...buying a modeling tutor!? <edit>ah! you sell tutorials. nice marketing...</edit>

@wing: don't let yourself get discouraged. did you only use vertex animation? i don't even know how this works in blender. have you tried to use bones already? with them animation is much easier once the model is rigged. you can also use a lot more polygons (for example to define the face a bit better) nowadays even if your target are quite old computers. better don't use automatic mesh reduction since it messes up the topology.
