Sounds like a fun project! How about a modern PMC persona with a twist? Here are a few ideas to get started:

1. 
   The Urban Explorer:
   Imagine your persona as a modern-day explorer of urban environments. He could wear a rugged jacket with lots of pockets for tools and gadgets, maybe some cargo pants, and sturdy boots. To add a unique twist, you could give him a signature piece of equipment, like a grappling hook or a drone.
   
2. 
   Tech Savvy Specialist:
   Your persona could be a tech expert, always equipped with the latest gadgets and gear. Maybe he wears a sleek tech vest with built-in compartments for all his tools, and he's never without his trusty tablet or smartphone. You could incorporate futuristic elements subtly, like glowing accents or advanced materials.
   
3. 
   Stealthy Operative:
   Picture your persona as a covert operative, blending into the shadows with his dark clothing and tactical gear. He might wear all black or dark gray, with subtle details like camo patterns or hidden compartments. Consider giving him a mask or goggles for added mystery.
   
4. 
   The Retro Futurist:
   For a unique twist, you could combine modern and retro elements to create a persona with a nostalgic yet futuristic vibe. Think of clothing styles from the past, like trench coats or bomber jackets, updated with a modern flair. You could play with retro color palettes or vintage accessories to give him a distinct look.
   

Feel free to mix and match these ideas or come up with something completely different! As for colors, you could consider earthy tones like olive green, charcoal gray, or navy blue for a more subdued look, or maybe brighter colors like orange or teal for a pop of personality. Can't wait to see what you come up with!
