|I noticed that you posted this story last November and that it was never reviewed by anybody and you never posted anything else. I hate to see that, so gave it a read. I think you did a very good job and have an interesting story going. The basic plot is interesting and you demonstrate good storytelling skills. I do have a few suggestions.
"Unfortunately for young Steve, he was only used to shooting the rifle while it was leaning up on the fence" Perhaps it would read better if you said it was "supported by the fence" or "propped up by the fence?" As written, I get an image of an unattended gun leaned against a fence.
"Steve took aim at an older, more slower moving rabbit," should simply be "older, slower moving."
"extremely hot, hence why the boys" I think the "why" should be dropped.
I suspect you aren't checking into the site often after going so long with no comments, but when you do get this, if you would like me to continue through the piece and offer further assistance, just let me know. Hang in there and keep up the good work. I look forward to seeing where this story goes.
