Design of the day — Sidera Design wallpaper

After read­ing this post on Smash­ing Mag­a­zine, I decided to par­tic­i­pate in this chal­lenge of design­ing some­thing every day. It doesn’t have to be a com­plete design every day, but the fact of learn­ing a new tech­nique or this web­site redesign is part of the chal­lenge.
So thus far, I have been design­ing every day, and today I’m post­ing a wall­pa­per image I created.
