What I express today is a sketchbook watercolor.
I use the art pen for sketching.
The pen is nicely smudging with watercolor.
I love the effect very much, so I played with this pen and watercolor a lot!
Summer is nearly over.
This blue sky sketch is a kind of good-bye to Summer!
Here are some products I used for this expression (including the art pen).
