I think everything looks ok, except the spine(?) (<- bones in the back where the thing has some meat missing in the torso area) which is textured very strange stretched over instead of textured...

Nice model. Well and I am not 100% up to date, but I thought model makers got themself more free and understood that a lifeform should have or had or at least have something between the legs. A metal plate or something. I saw alot of modern games which actually market that there is/was something. But some games still keep the "there was never anything between the legs" what I personally find ridicuouliciousescoious... damn word...
