Il y a combien deprovince au canada

Any french speakers? i need some . how would i say 'my oldest brother is very tall, interesting, and good at drawinng.' in french? would it be: mon (i don't know the french word for oldest) frère est très grand, intéressant, et bon à dessin. also, how would i say 'my dad is good at his work' in french?

Is this french sentence grammatically correct? "vous aimez dessiner, prendre des photos, jouer aux jeux vidéos et les animaux. alors, je pense qu’un jeu vidéo designer ou un informatician sont des bons métiers pour toi." should des be changed to de?
