There have been lots of complaints about the lack of body style options. Larian once had a reason for that, but decided to not bother making different character models, possibly because that would require changing every single armor piece in the game to make sure they work on the different body types. Larian games have never had different character models which let you change height, weight, build. In fact, I can only think of a few sandbox games which let you change things like that.
To be fair, Beyond Divinity allowed you to change your character to be slim, medium, large, and muscular.
