A bosom friend from afar brings a distant land near!   "bosom friend" t听起来有点过时。good friend 比较当前。但是我觉得这个句挺可爱，表达很好的意思。我好喜欢。 <font color="#000000"> "</font>bosom friend" sounds a little old fashioned, good friend is more modern. However I think the sentence works well as it is. It expresses a very sweet sentiment, I like it.

Hello, First, thanks for coming to my space. <strike>I am a normal girl with normal looking!</strike> I'm a normal looking, normal girl (但是太谦虚了，ok, but it sounds a little too modest）. I like English and hope to <strike>imporive</strike> improve it. <strike>and also if .</strike>  Also, if u want to learn Chinese then i can be ur teacher+friend!

平时用 you 和 your 但是在网上很多人用 u 和 ur，所以没关系，都可以。We normal use you and your, not u and ur, but many people use u and ur when speaking online or texting their friends on their phone, so don't worry, you can use this as well.

你有很特色表达自己得法。很好。
You have a distinctive way of expressing yourself, very good.
