Zoe we meet again, Mr. Voss.This will probably get moved to the proper thread, like you said, it is in the wrong one. No matter, that has been happening a lot lately.
I will proceed to give my inexpert and pompous opinion.
adverbs should be avoided if at all possible--I learned this the hard way. I would lose 'brightly' from the first sentence and sneak the name of the city in.
I dont believe you should call it 'the castle' before we have been introduced to it.
Dont tell us he can see the people down below. Show us.
The tense on this piece is unusual. I would use a more standard format.
The scene described lacks action, and in fact seems to purposely drag the tempo. so far we have a prince sitting in window, watching people below. Not that interesting so far, granted that this isnt a short story so it can develope a little more slowly.
Even for prince christopher Fitter wishes he was...I beleive this sentence is a little confused and could use work, and some punctuation at this point 'plague his mind wondering'.
What lifestyle was he envying? The adventure and grand discovery? To envy the lifestyle doesnt he have to have a specific example--never mind.
This thread is for improving your first thirteen so they will grab the attention of a publisher, so I hope my criticism is welcome.
It has been said that you should start a story as close to the action, or impending event that effects your MC, as possible. This isn't it. I'm sure there is something more compelling for your character to leave his current life behind than sheer boredom.
What is the straw that broke the camels back? An embarrassment at court, an arranged marriage to avoid?
Boredom, as the life changing event, that the first thirteen focus on, only begets boredom.
