Quick studies are usually small shots done in between larger assignments. I try not to spend more than an hour on each so I learn about the most essential controls to be used and not waste time in Maya. I love doing quick studies because it takes a lot of the pressure out of animating for me. It allows me to make my mistakes and test out different work methods while studying the principles!

Here's another hand study done super super quickly in class. I'd say it took about 20 minutes
Below is a "cushion" study in a simple head turn.
Below was an overlapping study and I felt like adding a little character to make it fun to create. hehe!
