Love the shading

This was like some form of rock like robot here, you have some "INTENSE-SHADING" here on this one, makes it even look like some sort of "ROCK" like look here, Some of those shades might even look pretty intense with some added color, overall this was just some really nice work and a nice robot like character, so keep doing what you do best, this was an intense visual and I have enjoyed reviewing it.

~~THINGS TO IMPROVE ON~~
Some added color would look really good on this.

I think this is even better then the other picture! Granted, it's still not good enough for me to give the full score to. It looks like the entire thing is made of rocks. I'm not quite sure what that has to do with the leviathan. I love the pose as well. There are just so many individual parts that all look great.

It's the kind of thing that you can look at and always find new parts. I just now notice the gears and realize it is mechanical. It seems like its legs are just gears themselves! I realize how much work you put into it. I can't tell if there's a second gun on its head.

Badass!

I like it. It looks very big. At least more than 5 times bigger than a human.

OMG METAL GEEAAAAAARRRRR!!!

Nice work again, I really like your attention to detail and this one isn't near the edge of the paper. xD Just some advice though when trying to draw things that appear huge, try adding minuscule features on it, like tiny scratches or small manually operated weapons relative to its large structure. The turret gun on it helps establish size as relatively large in comparison to a human. Nice work!

awesome

awesome robot. i cant draw half as good as that, keep it up! the mounted machinegun looks a little underpowered up there, no?
