A story of Robertus, a knight from Normandy

Salve!
I am just a beginner to Latin. I am currently at caput 6 of Lingua Latina, vol.1

I wrote this composition, trying to utilise everything I know to paint a story about a knight in the service of Duke of Normandy. I frankly admit to use Chatgpt at a couple of places to look out for new terms that I don’t know (they are highlighted), but I always try to write it on my own. Here is the text:

I would like to receive your feedbacks, suggestions to improve the story. If you ever come up with new and more advanced expressions, please leave some comments as I am very glad to learn more from the sides.

Robertus, qui est eques ducum Normanorum, venit ad Angliam cum suus servis. In Anglia, multa castella dominum anglicorum sunt. Guilelmus, Roberti dominus, in magnum castellum habitat cum ea familia. Mathilda, Guilelmi uxor, pulchra femina est. Habet dominus tres filios. Bohemundus est > ferox proeliator> , Henricus amat poesim et > vult fieri > episcopus, servus Dei. Guilelmus II > vult ire > Ierosolymam cum rege Francorum. Robertus Bohemundi bonus amicus est. Robertus Bohemundum invitat in Franciam. Duo amici ad Franciam eunt et torneamentum vidunt. Uterque equites laetissimi sunt. Bohemundus videt unam pulchram femininam. Is dicet: “In nomine Dei, hoc tornaementum vicam tibi.” Pulchra femina plorat. Bohumundus sumit lanceam et vincit torneamentum. Robertus Bohemundusque laetissimi sunt. Bohemundus florem dominae dat.

A few basic corrections:
cum suus servis: you mean suis? but better omitted
dominum: dominorum
in magnum castellum: in magno castello (or delete in)
cum ea familia: delete ea
vidunt: vident
Uterque: utrique
unam: delete (or use quandam)
dicet: dicit
vicam: vincam

Thank you, I appreciate your help.
I wish to ask: Is ferox proeliator the right way to say a “fierce warrior” in Classical or Medieval Latin?

dominum: dominorum

Thank you, is dominum even a word?

In Anglia, multa castella > dominorum > anglicorum sunt

Is that. correct? To have 2 nouns in plural genitive close to each other?

You can check on Logeion: proeliātor begins to be used with Tacitus.

dominum is the accusative singular of dominus

anglicōrum is the adjective that agrees with the noun dominōrum. It’s medieval Latin, but perfectly fine here. Adjectives must agree in number, gender, and case with the nouns.

You can look for warrior in Smith English-Latin lexicon.

Thank you!
I would put into use these dictionaries and lexicon. I didn’t know that Logeion offers Latin. Wonderful!
