Gig Summary
About this gig
Most concept artists sketch mechs. I build them.
I'm Héctor Castrillón, Senior Concept Artist with 7+ years specializing in sci-fi hard surface design robots, mechs, vehicles, and weapons. My pipeline goes from VR blocking and ZBrush sculpting through Blender rendering to final Photoshop illustration, which means every concept I deliver has real 3D structure, correct perspective, and production-ready proportions.
What this means for you:
- Mechs that actually look like they could be built not floating shapes
- Consistent multi-angle coherence from day one
- Files that work directly with your game engine or print pipeline
I've designed for: indie game studios, TCG publishers, board game creators, and sci-fi IP development projects.
What I can create: Mech & Robot Design · Vehicle Concepts · Weapon Systems · Hard Surface Characters · Props & Equipment · Sci-Fi Environment Assets
️ Message me before ordering your project deserves a custom approach, not a template.
Delivery style preference
Please inform the freelancer of any preferences or concerns regarding the use of AI tools in the completion and/or delivery of your order.

I'm Héctor Castrillón, a Senior Concept Artist with 7+ years in sci-fi hard surface design — vehicles, mechs, weapons, spacecraft, and book covers for games, publishing, and product development.
My process is hybrid: 3D-aided pipeline (VR, Blender, Substance Painter, Plasticity) for structure, then Photoshop for final illustration. The result is concept art that looks production-ready and holds up under scrutiny.

Hector was asked to transform 2D concept art into a 3D model. He went above and beyond: The finished model wasn't a thoughtless transition; it was an enhancement of the original idea without sacrificing what made the original concept interesting.
