My Ellipses Are Sealed

I decided to work on ellipses today.  I did two studies with a round doughnut (an Audi Stanton incredible in-edible) and a paper coffee cup. Then I added water and tried to make it look like coffee. (I am too hyper as it is to drink caffeine so it is not in the house).  There were a few ellipses in the setup.

Here are my two pieces. I still struggled with them. I keep over analyzing them.
