Hi there,
I have read the requirements you need and looked on the images attached. Perhaps I can help you with what you need.
I have worked on Unity as a Game Level Designer. This includes building environments for Architectural Visualization, AR, User Interfaces and the likes.
Apart from Unity, I also work as a Graphic Designer and adept to using Adobe Photoshop. I have also tried using Sketchup as part of providing assets to Unity Environments.
Please follow the link on my profile portfolio.
I have some few questions though:
1. Is there a Unity Scene to be provided, or is this built from the ground up?
2. By providing the high-quality screencaps, will I be providing just the image of the textures and screenshots of the Scenes?
Just let me know what you think.
