Best way I can think of to tell ya what to fix, is to show ya what I've been working on for a while now when I feel like going back to it since it's really just an experiment for me. I'm guessing most of his body will be covered by armor since he's a warrior, so you really won't have to worry as much about his fur more than what's there already anyway. His head... Roz got me on this too, so I share with you

Widen it up! Take his head, and scale up the x axis quite a bit. Make sure you tweak the neck to meld with it as well. His hooves... I've not played with the M4 creature stuff just yet, but the V4 ones have a morph for making the hooves bigger. Jack it up a lot, they have big feets! I wish there was a way to (pardon the pun) beef up the legs so they didn't look so puny compared to the rest. M4's might, so make sure you check for that too. Hmmm what else... oh hair! Not sure what kinda hair your man has in game, but if nothing else make sure you get that hair going down the back of the head/neck. There's no real way we can get that hunched look going that they have in game without some serious morphing unfortunately. I ended up using 3 different hairs for my girl just to try and give it a really thick look in the back to mask that fact. Anywho, you're on the right track. Hopefully it doesn't give you too much grief

Oh and ignore the naked state of my gal's skin. I haven't gotten back to her since I bought some cool fur shaders that just might do the trick
