Don't worry, your English is very good. I know some other non English speakers and they use the Grammarly browser plugin to catch things a simple translation app wouldn't (if you use one at all). Heck, even I use Grammarly most of the time because it catches loads of simple mistakes and typos too.
Anyway, keep up with the art posts. Seems like you are a natural "crowd pleaser".
Thanks) What could you advise me?
Just try it and see... https://www.grammarly.com/
They have a paid version but there is no need to pay anything, the free one is great.
Thanks!
