Fixing the blocking animation
The first thing we wanted to change was the way his legs moved - we weren’t happy with the “frog-like” pose, so we made sure to keep his right knee turned inside.
The second cause for concern was the way his back and right arm jumped together with hips after he received the hit. We made their trajectories smoother and lower.
Also, in the previous animation, the fighter's back was pressed to the left during the block, which was good, but it didn’t turn back when he stopped. So we made his back return to the right of his pelvis.
And last but not least, there was a problem with the pose where his leg extended back. The character did not slow himself down - there wasn’t enough inertia. Even though the hit he receives is of the average strength, he needs a pose where he cancels the inertia of the blow.
So here is the final result.
