if u have enough vocabulary can try to learn some books, or news in spanish, there u will find the way u can use different kind of modism, and the correct use of gramatic. Also trying to listen songs in spanish or any kind of piece where u can listen the pronunciation.

You can improve your spanish, you will travel to spain, because it more important to learn a language, it is, be you live in the country of mother tongue, because it is where it practice and you are everyday with spanishs peoples

I hope you understand my english...
Emmm the first difference that i see between our languages, is the genre of the things. Our Spanish is a little bit complicate 'cause, for example, you may say "la mesa" meaning "the table" but you can't say "el mesa" just because "mesa" is a femmale(?) thing.
Then if you try to learn the genre of the most usually things. You will improve your spanish!
If you want i'd help you to learn.
