toki! kama pona e toki pona.
I think the subject is correct, but you can more easily just say "mi open kama sona e toki pona".
mi jan Pinsen, li lon ma Netelan. tenpo ni la, mi toki kepeken toki pona pi mute ala tan ni: mi kama sona e toki Epelanto. taso, toki pona li pona tawa mi kin.I am Vincent, I'm from the Netherlands. Currently I speak Toki Pona very little because I am learning Esperanto. However, I too like Toki Pona.
mi kin li pana tawa jan ante e ni: ona li wile kama sona e toki pona. jan ante ni li mama meli mi. taso, tenpo ni la, ona kin li kama sona e toki Epelanto. ona li pilin e ni: toki pona li pona ala. toki Epelanto li pona mute I also caused someone else to want to learn Toki Pona. This someone else was my mother. However, at the moment, she is also learning Esperanto. She feels Toki Pona is not easy. Esperanto is very easy
I think your TP text looks rather good, and I didn't see any actual mistakes... but it's possible that I'm a bit out of practice, so I would hold out for some other people's opinions.
