Your story is quite interesting. I have a few suggestions.
Firstly, rangers rely on stealth and concealment when they travel in the woods. It's unlikely that your character would be using a tent, but would spend his nights in a small, well-camouflaged shelter which he would quickly construct out of branches and leaves. His meals would largely consist of dried meat which he would have put into his knapsack before beginning his journey, thus eliminating the need to hunt. If traveling through enemy territory, he wouldn't use a campfire.
You should familiarize yourself with Gondorian and Elvish names to make your characters sound more authentic. Here's one website you will find helpful: www.realelvish.net
Have a look at my story "The Lucky Arrow" for an idea of how rangers operate as a unit or as individuals in the woods. Please observe age restrictions on my other stories.
I hope you find this helpful. I look forward to seeing your next installments.
Author's Response: Thanks for the tips. Like I said, this is my first story, even though I'm righting 2 more, and I wasn't quite sure how I was doing. Thanks again.
