Thank you all for comments.
Not all joints are legal. try to sqeeze robot arm trough beard. I thouth beard will be thorn apart but somehow it was not. Also clip do not fit 100% to robot torso. And Indian feather is pushed between beard and other bricks without any attacment, only friction.
Fantastic! And I am very pleased that you did it all without illegal connections. Most intricate birds I see are all with hands and clips attached to clips. You managed to make a whole flock that could be used in actual sets. Amazing work.
