Translation (it was a simple mistake so the lojban might not be understood):
You made a mistake; the first sentence is not a bridi because it lacks a selbri. I suggest "pe'i lo junla narju grute goi ko'a cu xamgu cukta gi'e banli se skina". And for the second one ti isn't appropriate because ti is "this here". The language of here is lojban.
It's gone 12 here, so I probably erred somewhere.
