texture: have they both got the same mat? (the 1 ma 1 thing in the materials window?) you could also try selecting all faces and applying the material again, if you havent already. other than that, I have no idea.
on to the model: top looks good. I would like to see the lower half a bit more, unless you didnt show that because you arent ready to.
In my opinion, the elbow joints look a little strange where the muscle reaches…its a bit too rounded with no elbow definition. (unless of course I am not see it properly in the image).
I think the nipples on the pecs are a bit too low…or it could be that they (the pecs) need to be enlarged a bit.
to me, the teeth look a little strange at the moment, but I cant quite see properly in the image.
I hope this has been useful. Reading back it seems like im being a bit harsh :-? I mean no offence to your modeling skills.
