*Don`t be fooled into thinking that using the loomis proportions will give you more realism.

*no. alone they won't. but as part of an overall setup scenerio they prove to be a useful tool for making a realistic figure and should be taken into account.

but thats the choice of the artist making the image. no one is going to make you use them or even make a realistic figure... you do what you want to do.*
