This took about two hours, completely by hand, all using the mouse - no graphics pad. I used eraser, the paintbrush tool, and the airbrush tool. Made in the GIMP too, and about 4 or 5 layers. This also works as a desktop, if you'd like!
Anyways, this was greatly inspired by Terracidal's 'Morning Breaks'. If you haven't heard his music, check out his channel on youtube: [link]
I really liked the feel the music gave me, the eeriness, the unceasing wind. I've had this drawing in my head for a couple of months, and only now did I visualize it.
