Well, it still isn't nice to say a story sucks and not say why or how it can be improved...
I would suggest having at least two heroes to the story. When there's only one hero, there's not a lot of dialogue. Except the one hero talking to himself. Also there isn't conflict - when there are two heroes, they can get into an argument, split up, one might get lost, etc. etc...
Another thing: Nothing is really captivating about running away from home "to see the world". Even so, at least the whole country should be after the escaper(s?).Maybe Tom Harley (and his friend?) should escape the army before a battle they know they will lose. It's really hard to escape an army base for one, and second, the army should be after the fugitives.But how did Tom Harley find out they were going to lose the battle? Maybe he knows someone in the other side. Heck, maybe Tom Harley will decide to switch sides.Maybe Tom Harley is in prison (was framed?) and he needs to escape from there. He wants to avenge the people who framed him. But maybe he really was guilty and wants to avenge the people who caught him. Like going into the mind of a madman. Hmmmm...... That would be an interesting scenario.This is just off the top of my head.
The point is, you need to get a really captivating plot, and I'm afraid just going on a trip to "see the world" just doesn't cut it...(Okies?
