Mmkay, I don't actually have either of your pcs to check in detail, but I guees at some explanations.
For the soft shadow, the one were it is very faint, you are high off the ground, and the dark one, he is very low. Closer you are to the ground, the dark the shadow, should be pretty obvious.
As for the blood, you may notice that a single dismembered joint bleeds more than one amongst many. That would explain why in yours (which have many broken joints) have little blood, and the others (which appear to only have a decap or some such) have more.
