I recently bought Mateusz Urbanowicz's Tokyo Storefronts book and found it hugely inspiring! I decided to make one of the sushi shops in 3D as a hand-painted texture exercise.

I wanted to have fun trying to mimic a traditional style digitally, so I painted the texture from scratch in Photoshop as if I was using watercolours.
I really enjoyed trying to replicate his style in 3d, I didn't quite get 100% there but the attempt was lots of fun!
