Hi I am an architect experienced in 3D visualization field. I do interior design with realistic renderings. I had done cafe/restaurant interiors before. You can look at them in my portfolio.
Why you should choose me? Because I give my designs a "soul" as if the space is alive and a photograph taken at the moment: Smoke on a warm coffee with a magazine opened on the table, some foods and drinks on the kitchen counter, imperfectly placed chairs, realistic warm light, harmonious furnitures with each other and milimetric rounded corners around every edge (None of the objects in real world has perfectly 90 degree sharp corners, so little people care such details but those small details give the biggest difference)
The process will be if you choose me: First, I will model the restaurant in 3D using the dimensions you will give. Then I will place 3D detailed furnitures, or model anything in 3D if you require a specific furniture. Then I will prepare materials, reflections, textures, lightning, atmosphere. Then I will send you first renders in draft quality (720p). After you review and I made revisions, I will prepare final renderings in HD quality (1080p). I will notify you at everyday that how is it going and I will send screenshots in the process.
