I will try to be objective
Viktor was always in touch during the work, providing timely feedback.
He was patient, the task turned out to be larger in scope than I expected, so I slightly missed the deadline, but the result was worth it, in my opinion.
As for the downsides, and unfortunately there are more of them
it's that Viktor gave me many revisions, which I completed, and asked for a little extra pay for it, of course I did not receive it, but whatever,
after that, I handed over the results of the work, Viktor disappeared and did not close the project, I had to contact arbitration to get my money, which Viktor was warned about a day in advance, but in the end, he got offended and started to make additional demands, such as I need to give some additional source files.
By the way, I designed a layout for large-format printing, as Viktor informed me, everything was printed, meaning all the necessary files were already with him.
I am very dissatisfied with the collaboration, although the project itself was interesting, I would very much like to see the result, I asked for a photo of the print, but this request was also ignored(
