Another personal favorite. This was my final high school project, took a whole year to complete, from the initial ideas to the final renders.
The main objective was to design my dream car, but one that would be believable, not too flashy or futuristic; create a 3D model; and design promotional posters.
The model has around 12,000 polygons, 2x1024² textures and 3x512² textures, all made from scrath using Photoshop, and was also converted to the GTA: Vice City engine.
See some sketches done during the design process here.
