As it stands, I am terrible at drawing both big cats and male anatomy, so I decided to do a few sketches for practice.
There are many mistakes, I don't need them pointed out. Seems flattening the head makes the cat look more like a cheetah. Top right looks a bit more like a leopard or jaguar to me.

Here is the reference photo I used to practice the body. The heads are all referenced from various cheetah photos on Google images.

Blah practice sketches are always so creepy and lifeless.
