I think that 'slim' is a highly subjective term and may carry different meaning when translated into English. Compared to Hrothgar and Roegadyn it is not a stretch to consider Midlander men to be 'slim' but they are still fairly bulky and depicted as such in concept art, cinematics and also within the game itself.

I do not think there is a strong demand for the unusual proportions that is being suggested by some posters within this thread. I think they would benefit from compromising and pushing for something similar to the specific artwork depicted in the signature of Lauront and numerous other posters, as that is seeing much more support and appreciation.
