This picture does not have all of Lang's forms. He does carry 5 forms (not unlike the Garou of World of Darkness fame), the two forms depicted here are Glabro (Hybrid), and Lupus (Feral).

In Human (Homid) Form, Lang stands 6'6", he is a bit lean muscled and slightly lanky, athletic and has dark black hair that reaches the middle of his back.
In Hybrid (Glabro) Form, Lang stands 6'8", still lean and lanky, a bit more bulk on his frame, with long, jackal like ears and 8 tails (as he has in every other form but human.)
In "War" Form (Crinos), Lang stands 8'0", he is well muscled and bulky, and relies heavily on bodily strength over agility and speed, this does not mean that he's not fast or agile in this form, quite the opposite, this form makes him far more dangerous, and is often the state used when training with others... (Touya, Avalore, Feng, or the Guardians) and to protect. Yuuhi is only 5'0, regardless of what form Lang takes, (s)he's still dwarfed by Lang.
In Beast/Dire Form (Hispo), Lang is far larger than any other, this form is his 'natural' state outside of human, and rings true to what a Loxy exists as, well over 12' tall and weighing close to 800lbs, this form is often taken when in dire circumstance (and tends to be Yuuhi's 'hide from the world' form whenever Lang is in it... its easy to hide from people in tails that are as thick as haystacks <_<;).
In Feral Form (Lupus), Lang is a lean muscled and long-limbed wolf-like creature with a jackal's features and 8 tails, he holds thick and warm fur, and often takes this state for relaxation purposes, (and because he makes a perfect jungle gym for Akihiko.) Yuuhi can often be found lounging and using Lang as a pillow when he's in this form, its also the form that Lang most often takes when Yuuhi (also in a feral state) is misbehaving.

Regardless of the form or shape, Lang is a well trained warrior, and ironically, a hunter of Dark Supernaturals. A recent addition to the traditional family line of the Enma clan, Lang has become an integral part of the royal family, acting as both leash and support for Yuuhi, whom is coming into an age to take on the role of Monarch to the Makai throne. While there is still some time before Yuuhi will have to take Yasha's place, much of the days spent learning how to be a ruler, are also shared in learning how to live, love, and grow with a family Yuuhi desired for far too long.

Lang has become rock and support to the chaotic mess that was left behind in previous endeavors, and with his presence, Yuuhi has matured substantially.

Fengzhou expressed to me that there was a disturbing amount of nakedness in my gallery and drawings XD While most of it was tasteful, I had to admit to him that I am NOT good at drawing clothes, he suggested using multi-layers to do so, thus, this is the result of trying to create a full body costume. My anatomy work sucks <_< But I enjoy creating these sketches either way!
