Robot from scratch - Part1: Lower Body

I decided to build a new robot for my animation. Due to the fact that I can't draw, I started this from scratch without any imageplanes or robot-reference (only a proportion imageplane). I'm using techniques that i've learned during the previous modeling, and until now i have modeled everything without looking up certain techniques or the like. I hope that I'll finish the model tomorrow so that i can start building the rig.
