A request, More for information. A newb looking to go way over his head.

Okay...So, Something happened this morning...And...I've gotten the sudden will to try my hand more in-depthly with what I'll call "Simcrafting"...

My Objective: Create a Half-Orc Sim

Now...I know I could just slap on some green sim, and call him and orc...But No, No, No...I don't want that...What I want, is more crafted to look along the lines of...Dare I say, The Elder Scrolls: Oblivion Orcs.

Now...My first Idea on how I thought about going about this was to use Marvine & Beosboxboy's BodyBuilder suite. But...Something doesn't feel right about simply an increased frame. Orc's have a different muscle make-up than humans. From reading, and just pure guessing. I'm assuming I will have to work along the lines of the Maxis' standard skeleton. Let's note, I've really got little to no practice in this field, but trust me, I'm fast to pick up, and learn. Just need...Steps in the right Direction. Anywho... What i'm actually requesting is, possibly help and information, perhaps even assistance if the need comes to it on Making multiple parts to create a Sim Half-Orc.

The Parts
A. (Confused on)The Body Structure.
I've done a few clothing editing tutorials, but none which edited other than what the clothing hid. I was going to try the Body shaping tutorials at MTS2...But, sadly, all that's there is "FF" on that page...-Sigh.- So now, what I'd like to do, if figure out how exactly Beos/Marvine pulled together a structured body, which was easily reuseable to create more clothing. I need to know what files are what, who to export where, and so on. Anything easily accessible via tutorials I won't ask to be posted here. I'm really trying to seek uncommon information which isn't likely to be found.

B. (Easy, Can do myself.) Creating Custom Skintone, Eyes, and other textures.
This. As I said...I can generally do myself. I've plenty skilled at graphic's design via Photoshop, and the like. This one's no problem. It's just possible mapping problems that I may run into in the future.

C. (The Hardest for last.) Custom Orcish Facial Structure.
This one's the one which is most likely going to kill me. The Orcish facial make-up is different on compared to the Maxis' standard human face. I've seen very few, if any successful, mods which can actually pull off a good looking facial modification. The orcs in the picture are what I'd like to go for. -Sigh.- Man this is gonna be hard.

But anyway. This is what I wanna try and make my project, most likely my one and only...Hopefully SOMEONE Out there likes Orcs. =3...I mean...We've got Elves...Squid people...Dragonkin, Lizards, cats...But no Orcs!
