I drew a skeleton of Peach from Mario Brothers. Peach is like a human so she has most of the bones we have. However, she is very tall and skinny. I made her torso longer than usual and her fingers long as well. I made her neck long too, because it looked like if it wasn't, it wouldn't be proportional to her body. Her eyes are very wide. That's why I made her eye sockets larger than an actual person. Also in the photo her lips were apart. Like making an "O" shape. I had to imagine hat your teeth would look like without lips. Not as pretty as you would think.
