I think the assassin's creed one is great, though the Half-life one has a bit too much on the lighting, try darkening it a little.
Creed looks like prince of persia with them blades... Nicely Done my friend I also agree that Half Life looks a little lost in the light... unless that was the intention. Your loosing the effect of the blending in the excessive light Well done...
Like what your going for , but the renders are abit to blended imo and its to muc lightning in the hl2 otherwise then that GJ and KIU
well, the first one has lots of points with so much lightning, but it has dark points to, and that isn't good :S the second one is better, but I think that you've saturated it a little bit sorry for my bad english ^^U bye!
