Still, I would recommend you to learn some more complex modeling program, like Blender3D (if want something for free) or for example 3ds max if can afford it. I've never used MED for modeling, but I can imagine how hard it is to create complicated models and animations, e.g. the main character model or high quality weaponry. You made the barrel and the axe in 30 minutes. In 3ds max you are able to accomplish the same task in less than 5 minutes and then up to 10 minutes for texturing.
Just my opinion.....:)
