A cup of Joy (or Serenity ?)

Hello !
After watching that great class (thank you Amandine!), here is my take on the emotion Joy, which in my opinion ended more like Serenity. I think the colors are not as bright as they could have been for illustrating Joy.Plus, the idea of having a cup of tea is not exactly illustrating an exhuberant joy!
That being said, I think that it could work for illustrating a happy then quiet moment.
I chose to make a cup of tea because that usually is a happy moment for me, and thought about a thing that brings me joy: the first thing that came to my mind is being among nature. So I added plants in the cup. Those little clouds of warm adds to the feeling of Comfort.
Here is the first quick draft and the color chart :
... and the more refined sketch.
Perhaps one day a full illustration? :)
