Is plagiarism with themeforest a sin?

Question

HTML

Hello!
It just so happened, I got sucked into the topic of layout, and now I’ve been spinning around in it for 4 years already.
For services, they mainly turn for full-fledged templates for CMS from scratch, etc. I work alone (no, not that I'm greedy), then the layout designer, "designer" and adapter are one person - me.
But the problem is that I'm zero in design. No, of course I can distinguish bad design from good, I understand the basics of usability, how to do well and how bad. But when it comes to creating a layout, it turns out kkkk al. Well, out of desperation, I just go to themeforest, looking for suitable templates. I take one as a basis and supplement with elements from other templates. No, I don't copy the code and styles and paste it into the project, I take it and typeset it again, as if I'm typesetting from a layout.
Well, then I sell the work to clients under the guise of unique new sites or templates. If you open my site and the base site, then yes, you can notice something similar, but this is not 1 in 1 work.
Similarly with behance or dribble
Based on this, the question is: am I sinning when I do this? Gods of layout and design will not punish me later?

Answer 1

Congratulations, you have reached the point that almost everyone, and maybe even everyone, does. Now all that's left is to deal with it.

Answer 2

It's ok, a lot of people do it. I don't see anything wrong with that. I always climb dribble or temporest for inspiration. sometimes just to understand what I want, sometimes to borrow some bits.
