このサイトにようこそ、同国人さん。Your Japanese seems pretty decent already. I wish mine was as good at your age.
I think there is a small mistake in what you wrote though:
・「日本語を悪いだね」--I think を is the wrong particle to use here, as 悪い is an adjective not a transitive verb.
I was going to list another mistake, but I think「日本語勉強してます」is completely fine for casual writing (dropped particles and stuff), with the full form being 日本語を勉強しています. ~してますnearly caught me out. I know about and have seen してる used instead of している, but I haven't actually noticed してます being used for しています before now. ^^;
