PowerPoint Editing with Wild Animal Silhouettes

I need a PowerPoint presentation edited to include simplified silhouettes of wild animals in the background. The animals should be subtly muted so they don't overpower future text copy I will add later.

Ideal Skills:
- Proficiency in PowerPoint
- Graphic design experience
- Understanding of visual composition
- Experience with creating or editing presentations

Please provide examples of similar work you've done in the past.
