Need 3D Graphic Design -- 2

I’m brand-new to Freelancer and want to kick things off with a distinctive 3D graphic. The concept is open—what matters is that the finished piece feels polished, professional, and ready for use across both digital and print channels.

Here’s what I’m after:
• A single, eye-catching 3D graphic delivered in high-resolution PNG/JPEG plus the editable source file (Blender, Cinema 4D, or comparable software is fine).
• Colours, lighting, and perspective that hold their quality on social media, websites, and large-format print.
• At least two rounds of refinements so the final piece matches the vision we agree on.

Please share a sample of similar 3D work and let me know which tool you prefer to work with. I’ll review portfolios quickly and move forward as soon as I find the right match.
