All it needs is a skin and some construction animations. I am planning on finishing the animations by this week, but I am not able to do the skinning because I do not have PhotoShop or anything like it. Anyone who wants to give it a skin can email me and I will try and give it to you by the end of the week.
I think you may be right about the top. Now that I have compared them together I can see a difference and I will fix it, which will be rather easy. I love editable meshes.
