Creating is like breathing to me. It's what I do. It's what I have to do, and most of the time I create worlds. They are abstract worlds that look like everything and nothing, but to me they are nebulas, pouring rain, skyscrapers, the bottom of the ocean and northern lights all at once. To you they might just look like pretty colours. It doesn't matter. These creations are what you want them to be, which is why they make me feel so free.
The technique also adds to the sense of freedom, as making it all digitally enables me to change and enhance them until I'm completely happy with colours and expression. Creating is like breathing to me, and my abstract art lets me breathe freely.
