Glorious Feet

So I've been reconsidering my original design for the aliens feet, I wanted to have a reptile look for the feet so I looked to incorporate a Velociraptor claw to a humanoid reptile look for the rest of the foot, though now I'm not so sure it looks all that good, it isn't aggressive enough. I have been keeping a basic boot design as a back up but I haven't given up on the reptile look. So I'm now experimenting with creating a foot design based on the Tyrannosaurus, this will give me the aggression I want as they have rather large claws which is something I have really seen this alien species having as an integral part of their fighting style.

This is the initial results of the new foot design, and I have to say that I'm really pleased with how this looks as oppose to the original idea.
