Beautiful work. I love your mix of gentle curves with straight lines. They seem easy on the eye, which perhaps belies what they are capable of doing. I really like what you did with the arms, feet, head and chest, in a combination of shapes that is humanoid of course, yet not a straight up and down framework. Like I said earlier, easy on the eyes since it makes the eye move around. I like how it looks functional and yet artful. From some of the comments I see it stands very tall and given the look, it should work as you described. Something approachable, yet very capable of doing its designed job. As with your other work, I love how you think it through.
These guys patrol around the streets and people with problems come and approach them so they can't be scary. And if some illegal activities need to be stopped, who cares how they look when they're over 2m and 300kg. I have a very finnish perspective on police forces
Special forces and riot police, now that's a different story and I need to do those someday.
