I'm really glad to get feedback from English native. I'm even more happy because your feedback confirms my expectations: articles are really hard for me, because my first language does not have them.
I'm a Spanish native speaker and I also have problems with articles, but it seems like I have the opposite problem, it seems like Spanish uses articles more often than English, so I usually add them when they are not required, maybe not grammatically incorrect but sometimes I could sound kinda weird.
