3D Concept Design & Photo Renderings:Stroller w/Custom Cover

This project will involve creating 3D models and renderings of a current baby stroller model with several changes. The models will be constructed from a real picture of the current model. The designer will have to: 1) Build the base model in the 3D rendering program of their choice A) Make the requested changes to the structure in the 3D model given at the start of the project B) Create 4 different special fabric 'covers' specified that fit onto the top of the baby stroller that will be rendered to look like nylon fabric. 2) Create photo realistic renderings of the final approved design with the four different covers from multiple angles with requested text in each shot. The designer must be experienced in 3D modelling and rendering of metals and fabrics. Please send examples of photo renderings done from 3D models, especially showing creative talents and the ability to render realistic looking fabrics.
