Lego batman bat mech (76117 optimized version)

After observing the official set 76117, which I personally like very much, I spent some time during the day and did some modifications to it.

The official set is literally beautiful enough, but I still have my personal preference in many details, especially proportion aspect.

Here are some changes I made:

(1) Boosters on both shoulders, back and heels.

(2) Head repositioning

(3) Legs (standing straight)

(4) More armor

(5) A chain-connected circular saw

(6) A great katana

(7) More small details in the cockpit
