I have come across this process before but your class broke it down further so I understood it a bit more. 
I found the cheetah the hardest as I wasn’t sure how to approach the body on the angles. Was what I did correct?

I surprised myself with the dog as I usually struggle with out tracing the outline so I was pleased with how he came out and did notice I was paying far more attention to using other body parts to scale everything. Starting with the body does help.
