Only red, a lot of red, will do right now. And it absolutely will be oil pastel because of how it feels. It is rare for me to know such things before I open my art journal to the day's page. Well then, okay, away I go.
The result: a red (sort-of-a) horse
Mixed media - oil pastels, ink, paint pen, gel ink.
I love daily art journaling because it is there to catch the unplanned, the fleeting. Where would my red horse be otherwise?
