Study Task 4- DUIK

I decided to use my character from my animation for the DUIK study task, setting up the character and adding the bones to the character was the easiest part for me, apart I was unable to pin one of the bears legs at first which took a while for me to try and figure out what was wrong. My other problems with using DUIK was the controller for the head didn't work and when I tried to use the quicker option instead on keyframing my puppet didn't work either, so it took a little longer than it should have to complete this task
