Topology question (Hard surface modeling for cinematics)


Hello awesome people. Hope you all guys doing well and wish you all the best in coming year.

I have couple questions regarding hard surface subd modeling for cinematics.
I practice modeling complex items and stuck with some basic staff I guess.

This is reference image that I’m trying to model

  1. Should it be a single piece or I can split it on simpler meshes? Something like on the image below.

  1. Another question regarding topology. I stuck with corner area and have no clue how to solve the topology (only quads) that is highlighted on the images below.

Thanks everyone for reading my post and happy new year.
