I'd like to comment on the story instead of grammatical issues, but there's really not much there yet.
There are a few sections where you're pretty redundant. You should try using a wider variety of words. For example, you use the word "forest" four times in three sentences. When you get passages like that, try using synonyms or pronouns instead of the same word. I actually don't understand the first sentence "To the South and West of the (don't think this should be forest) was a thick, dense forest. The first trees of the
wooded area weren't too far; a quick sprint and he could reach them in no time. However, if he were to sneak to the
cover of the trees without being noticed, he needed a diversion."
That's another thing. You started a new sentence with "but." You shouldn't open with conjunctions (so my professor told me). Instead of "but," use however followed by a comma. For and, use in addition.
Is this the beginning of your story, or just a section you wrote out and decided to post?
Whenever you get more, you should post it. I'd like to see what the rest is about.
Read mine?
