it's not awful, but needs development. By the second paragraph, we know where he's going, but only know he has brown hair. He comes upon a stand with wares, but no one selling them. Did he eat first? Did he just nestle in between the stalls and nap?
If this is going to be a short story, it's alright to reveal his task quickly. If this is intended to be a novel, you'll want to allow the character to see the world and perhaps give him some motivation before sending him on a quest. Why he is risking his neck is just as important as the actual risking.
Short story or no, a little background on the character would also be nice.
One of the most difficult things to do with an idea like this is to slow down with it and allow it to develop. Back to brainstorming. I'm a HUGE proponent of brainstorming. Write down everything YOU know about the character, the world, the Demon Queen, etc.
When you re-write this scene, remember, we're not in your head with you (though from your postings it sounds like an interesting place). If you can envision it, smell it, touch it, taste it, hear it, then put that into your prose. Use all five senses when describing a scene like a market place. This will draw the reader into your world. In your scene, there's one person at the start, and by the end he meets the blacksmith. Where are the shopkeepers, the livestock, the children, and the customers? Is it crowded, or empty? Is it a group of stands on the side of the road, or a set of buildings on a street in a town? Lots of questions to help you with your scene.
I understand the urge to jump into the thick of things. This is why I've taken to writing short stories for the time being (Up to 55 for the year so far). SOme brief introduction, set the scene, Give a little motivation, spark a conflict, provide a resolution (Those posting in the exercises don't get to remember that last part.

). I get to do all that in roughly 3000 words. For a novel, there needs to be much more character development and building of motivation for the characters to do what they're doing. More description of scenes. Interaction with others in those scenes. The dreaded explanatory text to explain what you cannot show. These are just a few building blocks of a story. It takes time. It takes patience.
My advice, don't try and write a novel. Work on short stories for a while until you get the hang of dialog. Work on short stories until you get the nack for description. Work until you can motivate a character and YOU get excited reading what you've written. A novel takes time (Years for some authors). Short stories can be done in days if you're motivate. Don't go for the big bang right out of the box. Entice your reader. Draw them in and introduce your character by interaction with his/her surroundings and others in your scenes.
I'm rambling. I've been doing that a lot lately, eh? I'll get off my soapbox and try to finish up 'The Pool'. I'm actually writing something that's making me laugh.
