Howdy! I love the character creator, but I have some constructive criticism about the character models. I guess this is a bit nit-picky, but I am an anatomist and noticed that the belly button is in the wrong spot. It's way too low on the belly. Below is a comparative figure I created to illustrate this point. The belly button in humans is typically in the middle of the 3rd row of abs (rectus abdominis), or at the very bottom of that 3rd row (model on the far right of the image), but in your character model (left in the image) the belly button is much lower, in the middle of a fourth row of abs, which is clearly not anatomically correct.
And as a side note those pecs also look a bit off, too flat for someone who is fairly fit and muscular, but I suppose that can be adjusted with the sliders. I am not so sure about the belly button though, so please make sure that you place it correctly from the start.
