1. Sketching
2. Polishing sketch (since it looked good enough, I just edited it to lineart stage) and selecting palette colors.
3. Adding Flat Color (Forgot to save the flat color stage) and cell shadows/lights.
4. Polishing color (softed the cellshade with an oil brush and added bouncing light with airbrush) - Probably you won't notice the difference at this size
5. Painting background (Used watercolor brushes and some stars stamps)
Thats all! Hope you liked it ^.^
