I need a polished, highly realistic exterior illustration that brings my new rollercoaster concept to life. The coaster would be from a side on view as if you are looking at it from the side. Colour scheme would be white with blue / red led lighting to showcase the futuristic vibe. There would be some lens flare / glare from the lighting from the headlights and the backlighting. No AI please. The coaster must look futuristic but also fun aswell and makes people want to go on it and go for a ride. This would be based off a sketch I have done and can share this with winner. Please deliver: • A high-resolution final image (minimum 6000 px on the long edge) in PNG • A layered source file (PSD or native file from your chosen tool) so small tweaks to colours or signage can be made in-house later • A brief note on the materials, references, and 3D or digital painting techniques you used, so we can maintain consistency in future visuals My price is around $20
