Thank you Kent. Your praise really pleases me. I am trying to give feedback from the process for lessons learned.
Today, I thought I could smoothly make 2 pieces. Machines were set up. Tools tested on old metal samples.
When I started to shape the first bend, the machine had a different sound, and the metal plate jumped more. It was very difficult to hold the plate in the correct position on the backrest. The profile cracked when I used the second tool. Yes, it's clear. I bought a hard sheet metall ..... The way is right but wrong material. You are never smart enough. Further lessons for the school lesson.
But I am also satisfied with the chosen procedure. Material 1 mm sheet allows grinding and polishing under chrome, it is sufficient thickness for further machining.

Witold. Thank you for your advice, but there are a lot of points that need to be addressed. Tool shape. 2 levels of shaping and slow adding depth. I was very reassured when I found out that I had poor sheet quality. I tried the principle - as always on old soft sheet samples. Then I bought a new clean sheet metal and everything was different.

The customer he saw the result, the customer has bigger eyes than he used to have in the past.
