hardest part

The arm is definitely the hardest part to model since it is a more organic shape compared to the other parts of the lego minifure, i didn't follow the steps from the demo but I did figure out a different way to build it.

After extrusion and fillet the upper arm, I loft a surface to cut the extra part

and then use loft to connect the the elbow to the end of the arm

extrusion to cut the unwanted part again

here is the completed left arm. I am happy with the overall shape although it is not the best quality.
