Don't get down.  Its an excellent debut!   I myself am not a content producer so I can really tell you how to do the inserting of pics, but hunt around maybe even here on steem.  I'm sure its not that hard.  Personal pics are probably best, but you can also use a online free pic library.  Choose the pics the convey the feeling you want to relate.   I'm not sure if you need to remove the post.  I know of some people that post raw first, and add pictures. .....then again some leave it raw, but I think you will get more traffic with pics, specially in your title heading.   Best.
