Let's take a look at these two
1. The colour piece with Galgo:

2. The concept art:

In 1, the predator looks bulkier and the armour looks more AvP-ish. The mask resembles the Lord Mask of AvP2010.
In 2, he looks leaner. The face is like Jungle Hunter's. I'm not opposed to that. The scarring is reminiscent of Wolf's. His armour looks more classic (not AvP-ish), same Lord Mask. He seems to have a ragged cape going on.
I think both are decent. I don't find the colour piece to be particularly more original than the concept art. The glaive, spear, axe thing looks cool to me.
