This is an example of how you can nicely visualize an interior fitting to your customer.

I've had to do and visualize a shop design and was looking for a fancy good looking, illustration type of style. So i created this room, accordingly to the dimensions from the architect, and designed the shop in there. (Unfortunately i can't share the completed shop design i did for legal reasons. You'll get the blank template you see in the preview). Cause i like the result i achieved, after tweaking tons of light and camera settings, i thought it would be nice to share this with you. Enjoy.
