How to correctly describe the layout of other people's layouts in your portfolio?

Question

Layout

What is the correct way to place "portfolio" of layouts (taken from public layout search sites, especially for Adobe XD (convenient))?
I learned to do various interesting things, including with scripts, plugins, that's not the point. But is it worth it to sign these layouts as "My Works / My Portfolio" and so on, without indicating the source and author of the layout.
Of course, I know how to design, I must admit that it’s not so easy, (I hope) there is a sense of beauty, although in its infancy, but I didn’t have time (at the beginning) to make my own layouts, and I also didn’t want to develop in this direction my.
Overly grateful.

Answer 1

And even better - write to the author of the design) Since before his death, according to the law, this is his personal right and some time, like 50 years before it becomes public. Here I xs, read the law.
By the way, ignorance of the laws does not exempt from responsibility, and the fact that dis and you in different countries is generally insignificant.
If you put a bolt on your conscience, publish with a link to the original. Or even finally hammer the bolt on copyright. Perhaps it will blow)
Plus, see the license. If specified, for example CC0 Creative Commons ( https://pixabay.com/en/%D0%B4%D0%B5%D0%B2%D1%83%D1...for the photo, see on the right), if it is clearly indicated there that you can use other people's work for free, with a reservation for commercial / non-commercial use, then here you are generally a topper)

Answer 2

If you are worried about authorship, write explanations for the work, that the layout is based on ready-made layouts using such and such technologies
