How to post that 1st article

I joined and got an amazingly positive welcome wrote my 1st guide and went to post and realised upon looking at my article with pics and links that I am not confident I will get the outcome I have seen from the articles I have read through already. I maybe just over thinking this but as a newbie I sure could use some help. I can post it and cross my fingers but that 1st step seems to be a big 1.
Help!!! 😩
