How the hell are you so good at animation!?!

 This piece is incredible. However, I think its convincingness would increase dramatically if you used some dynamic shading, especially around the cylinder part of its midsection.

 Yet again, the animation is exquisite, but the art could use a bit more polish :D

Damn, this is nice. I wonder how gorgeous it'll look like if you improve the shading.

 You pieces are made with so much love. I think you're my new idol.

 Damn this is awesome! The only thing I don't really feel comfortable with is the lighting and the metals texture :P

 must say first, beautiful animation. only issue i see is when it fires, the dirt pile on the left most leg disappears during the blast and pops back in once it resets. i would say try making the dirt stack up more on the left side, and when the robot returns to the start position, the dirt drops back down like a wave look. also the foot is off position by one up and right. great and super smooth
