Critique #2

http://oi58.tinypic.com/j9yrg6.jpg Overall good stuff, I'd say just make sure your lights and your shadow lead your viewer where you want them to look. Also your cross hatching, needs to accentuate the form a bit.

I like how the Human shows Fear towards while the Creature seems more Curios than Menacing towards the Human, also how the human in more in the dark, showing his state, and the creature is in the light ^^

That looks good. The only thing I can find that could improve is the anatomy of the face. The first thing that comes to mind is the forehead, how it bulges out. Maybe make it more subtle. The lips look really thin too, especially on the bottom lip since it sticks out. The overclip of the upper lip seems to be missing, though I am not sure if it is just the style you are going for. The fingers of the hand that is closer to the gun barrel look short... If you are going for perspective, maybe try enlarging the finger joints that are closer to the camera, to make it sort of "pop out". The ears may be a bit small. I would maybe make the shading of the underlip/chin area be smaller, to give it a less hollow look. The drawing looks very good otherwise, and I like the shading and fade effects.
