Is this the right french tense?

Question

this is the first part of my story i have to write so i was just wondering if it made sense, right tense, spelling, use of words, and stuff like that.
also if should be with passe compose and imparfait
thanks!!

David était un gentil jeune garçon. Il a les cheveux bruns et les yeux bruns. Il était intelligent et a aimé le football. Un jour, il a joué au football avec ses amis. Ils ont perdu la boule dans la forêt. David est allé le trouver.

Answer 1

Mostly, yes. Comments interspersed below:

David était un gentil jeune garçon. This is fine.

Il a les cheveux bruns et les yeux bruns. Good also.

Il était intelligent et a aimé le football. This implies that he doesn't like football anymore. If you are still describing, use the imparfait. But, if you are just saying that he liked football, it's OK as is.

Un jour, il a joué au football avec ses amis. Is this a done deal? One day he played football with his friends. Period? That's it? Did something happen while he was playing ball? If so, use the imparfait rather than passe compose.

Ils ont perdu la boule dans la forêt. David est allé le trouver. This is OK also.

What I'd probably say is something like this: Lorsque David et ses amis jouaient au football, on a perdu la boule .....
