I sense a clear feel for perspective in these robo-bean/structure poses, I really enjoy watching this, excellent work especially how you got carried away with the last pose haha, very creative. always make sure to check your boxes following the same vanishing point and mind the horizon line when working with more than one shape o nthe same perspective, that's all I have to say imo because you're definitely on the right track I think !

The middle one in the second image I instantely recognize Xavier Houssin's work, an artist that inspires me very much as well, my critique here would be more about exageration, if you observe the pose I mentionned on the original work you used as reference, try to imagine the simplest action line on it and observe how much Xavier pushed the gesture to make her more dynamic. Otherwise it is pretty solid work keep it up ~

it feels like you're still focusing a little on contour rather than movement/action some curves could be simplified even more, always remember CSI, but I can definitely sense a flow and energy in these sketches, you're on the right track !
