Hydrogen Energy Illustrations Needed

I'm seeking a talented illustrator to create two engaging images centered around the theme of hydrogen energy production. These illustrations will be used in a presentation and printed materials, so they need to be visually appealing and informative.

Key Requirements:
- Two illustrations depicting cross-sections of the Earth
- One showing the drilling process
- One illustrating seismic energy/waves
- Style should be mildly cartoonish to make the images easy on the eyes
- Moderate detail with clear features to ensure clarity and understanding
- Use a mix of bright and subtle colors to enhance visual appeal

Ideal Skills and Experience:
- Experience in creating scientific or technical illustrations with a creative twist
- Ability to balance informative content with an engaging, cartoonish style
- Proficiency in using color effectively to convey information and maintain aesthetic appeal

Crude sketches attached for reference.

I'm excited to see how you can bring these concepts to life with your unique artistic touch!
