Salam alaikum! plz check what i made.

وعليكم السلام ورحمة الله  :)
Hi, Good Job! :)


1. i love when you smile.
أنا أحب عندما تبتسم

You've missed a pronoun  the correct sentence is :-
أنا أحبك عندما تبتسم
If you want to sound more like a native speaker you should say :-
أحبك عندما تبتسم
or even better
كم أحبك عندما تبتسم!
Note that if you are talking to a girl you should say :-
كم أحبكِ عندما تبتسمي !
2. the man insulted here with a scandal.
الرجل شتمها مع جرسة
I didn't understand this sentence !! but I think that you are trying to say :-
شُتم الرجل غيبةً
3. you complained about the food.
أنت شكيت من ال طعام
There is no space between ال andطعام
In Arabic when we want to say that someone have complained about the food we actually say
أنت تَشَكَّيت من سوء الطعام
The word in pink means "bad" and if I translate it to English it will be like :-
you've compained about how bad the food was.
4. i hug him and kissed him.
أنا حضنته وقبلته
Again if you wan to sound more like a native speaker just say :-
حضنته وقبلته
for girls >>>> حضتنها وقبلتها
I'd say :-
احتضنتها وقبلتها
5. my friend has a good personality.
صديقي شخصية طيبة
I'd say :-
صديق يمتلك شخصية رائعة

Really good keep going

جيد جداً واصل التقدم :)
