Its good to be both an Artist AND a fursuit builder.. i can offer "profile Suit pictures" like this one of the StormWolf suit WIP. For a small fee, these can be done either prior or during the suit build, to show how the suit will look on a human form, and show how the fabric custom patters will look.
Thes profiles help alot for both the builder & commissioner to establish a plan on a fursuit build, for both to see and understand what the suit will follow. (though the resulting completed suit will have more details than these profile pics, as these are more for a reference of the suit design and style. It helps to when the builder can do thes pics, as fursuit builders understand how fabrics "come together" on a human form suit. There are many profile pics done i have seen that dont really follow practically how a suit needs to be done to fit a person, as they are based completely of a 2D fictional caracter, with the anotomy not very practical for a real human form.
...There are advantages of being both an Artist and a Suit Builder in these cases.
