Ok, before you berate Cruaich any further, you should have a look at the model ingame, rather than in a viewer that distorts perspectives.
The image has been brightened after the fact so that it can be seen clearer. Animation has barely begun, so this reference pose isn't even going to look as close to an original sprite as people might be expecting. The tommygun is obviously linked to the proper skin here (so if it looks bent then the pickup must be bent since they're the same mesh

) Fortunately for Predator the mouth animates, so the cultist won't always look like a slack-jawed grandfather.
Some of the criticisms may be valid, such as the long face (which I had concerns about before). I don't know about the arms, since if they're shorter he'll have a harder time holding the weapon without clipping. Maybe they can be a bit shorter. The legs probably look like they're too short because, well, I don't know. Anyway, have a look at this image
The head was modified i.e. squashed, and the legs were shortened (why? I have no idea why I did that, I should've done the opposite - having the model in the spread-leg pose doesn't help the view at all). But this pose is a bit more animated - the arms weren't modified in this case.
I don't have a problem with the skin as is, I think it looks great. But going from the last picture I posted (keeping in mind I'll extend the legs again), do the arms still need reigning in? Is the peak still too pointy? Is there anything else glaringly obvious (remembering that I've mentioned the legs already) that needs to be fixed?
