Something really strikes me as fake about that sketch. It just doesn't look like what a real primate would like. For example, the jaw and saggital crest: saggital crests are used to anchor jaw muscles, but the animal in that sketch has a tiny jaw. There also isn't any widening of the face liked you'd expect to see to accomodate jaw muscles large enough to make a saggital crest. Basically, a sagittal crest is ususally followed by a large masseter, mandible, and zygomatic arch, none of which are actually bigger in that sketch, despite the saggital crest being huge. The chin bugs me, too. It looks like the jaw recedes and then a chin jets out - it's very awkward, and not something I'd expect to see on a real animal. Either a jaw recedes (as with every hominin besdies us), or there's a chin (like with us), it doesn't make sense to see both traits mixed. The forehead is pretty strange, too. There are weird bumps that seem like they might indicate a brow ridge, but they're way too high, which would mean they'd have to be muscles. However, there's no reason for muscles on the forehead to need to bulge like that, and I've never seen it before, or anything indicating it on a skeleton.
It just doesn't make anatomical sense, IMO. It looks like someone cherry-picked human features and ones usually given to bigfoot (and apes, I guess) and threw them together to create an ape-ish human. I guess it worked, since a lot of you seem to buy it, but it can't. It just looks like an awkward mash-up of features that does make sense. Not a real animal, just something thrown together by someone who doesn't know a lot about primate anatomy.
