Making custom AE template based on premium, is this ok?


I have relatively big YT channel (selling beats) for the last 5 years.
I am pretty aware of copyrighted material.

I have started 4 new YT channels and want to buy few templates from this site :slight_smile: for specific video, used one time.

But, I want to also use one simple call out template which is selling here.

Using YT tutorials, I have made, lets say 99% the same look and function of the Envato Call out titles template.
It looks and works the same, but I have made it myself, from blank screen.

REASON: I want to use it in my every video whenever I want.

Would I have troubles with copyright or something?
Again, I made it myself, but it looks and works like the one selling here.

Thanks a lot for the answers!
