First notebook entry: Introducing myself

你们好! 我叫安尼. 我是英国人. 我已经学习汉语两年. 我现在想跟母语人练习汉语. 我还可以帮助你学习英语. 我很喜欢学习语言, 但是我觉得汉语是世界上最难学的语言, 所以我需要你的帮助.

I don't know this is your Chinese composition or just a message you left here, anyway, I think you've done very well. I don't think there's any other mistakes except the RED and the "但是“。 For the RED , the correct one should be "母语是汉语的人” or just "中国人“。For ” 但是“ ， you should know that a sentence begin with it usually expresses just the opposite to the prior one.  And here obriously    "我觉得汉语是世界上最难学的语言" and "我很喜欢学习语言" has no contradiction at all，therefore， you know, just get rid of "但是” or replace with an "and" , it'll be much better.  

Your article is pretty good except for the two mistakes.  Unlike others, I think there's no necessary to make your article a perfect one published in a magazine or books. We Chinese also write something exactly your way. Two things you need bear in mind in learning a language:  confidence to face doubt and respect to the language itself.
