Assuming you would like tips on how to paint a blue and green peacock standing on grass:
1. Begin by sketching out your peacock. If you're not confident in free-handing, you can print out a reference photo or use a light box to trace.
2. Once you have your sketch, start painting in the blue areas. You can use different shades of blue to create depth and dimension.
3. Once the blue is complete, start painting in the green areas. Again, you can use different shades of green to create depth and dimension.
4. To finish, paint in the peacock's eyes and beak. You can also add any final details, like grass or flowers.
