Assuming you want a step-by-step guide:
1. Begin by sketching out your pelican and rock onto your canvas. You can use a light pencil to help with this.
2. Once you have your sketch, start painting in the gray color for your pelican. Make sure to leave some white space for highlights.
3. Once the gray is dry, start painting in the brown color for the rock. Again, leave some white space for highlights.
4. To finish up, add in any final details like the beak and eyes. You can also add in additional highlights if needed.
