I have seen saw 'The Avengers' last month. I like the character, Loki this character so much a lot, as I like the actor Tom Hiddleston.

OR, you may write like this:
I saw the movie, 'The Avengers' last month. I like the character, 'Loki' as I like Tom Hiddleston

I published a micro-blog about Loki & Thor with a picture the day before yesterday. What surprised me was the number of forwards, which has grown to more than 900!

It never happened to my personel personal micro-blog.

I felt excited there were many people like me who adored(I have a question that should i use the past tense to the "adore"?) Tom Hiddleston.

I felt excited that there were many people like me who adore Tom Hiddleston (I think you can use adore. not 100% sure. will confirm soon)

And I followed the micro-blog of England News and The Cate of London today.

I have never went gone to Europe before, I think there is different culture from our East.;)I have not been to Europe yet, and I think it has a different culture from the East :)

Tommorow I plan to draw some pictures about of Loki or Tom for myself,ehehehehehehe...

forwarding -
visits?
shares?

It has never happened to my personal micro-blog before.

I felt excited there were many people like me who adored(I have a question that should i use the past tense to the "adore"?) Tom Hiddleston.

You can say
who adored Tom Hiddleston.
OR
who adore Tom Hiddleston.
Either is fine.

I have never been to Europe before, I think there is different culture from our East.;)

My summer holiday is here.

I don't have any plans for my holiday, even through I have many intrests.

I pulished a micro-blog about Loki&Thor with a picture the day before yesterday. What surprised me was that the number of forwarding grew to more than 900! It has never happened to my personel micro-blog.

如果你用"adored"别人能觉得人们现在不喜欢他了或他死了。=/

I want to go to Britain to study design knowledge.

I have never gone to Europe before; I think they have a different culture from our East.;)

"I think their Western culture is different from our East" is closer to native speaking, but...

我想那应该有不同于东方的文化 => I suppose Western culture should be different from our East.

Tomorrow I plan to draw some pictures of Loki or Tom for myself,ehehehehehehe...

My summer holiday is here.

By "summer holiday" do you mean a few days from work/school, or several weeks from school? Here we would call several weeks off from school a "summer break".

I don't have any plans for my holiday, even though I have many interests.

When you use "any," use the plural noun after it: "any plans, any cats, any papers, any buildings".

I almost stayed at home all most of the day, so I haven't yet experienced more many things yet.

I assume you meant "most of the day" when you said "almost all of the day". :) Correct me if I'm wrong!

To say "more things," you have to have experienced something already. You didn't say you experienced something else, so I changed it to "many things".

"Yet" sounds more natural at the end of the sentence.

I have seen saw The Avengers last month. I like the character Loki this character so much as I like the actor Tom Hiddleston.

I pulished a micro-blog about Loki&Thor with a picture the day before yesterday. What surprised me is the number of forwarding views grown grew to more than 900! That has never happened to my personal micro-blog.

I felt excited there were many people like me who adore (I have a question. that Should I use the past [or present] tense to the of "adore"?) Tom Hiddleston.

They (and you) still "adore" him, so it is not past tense.

I want to go to Britain to learn about designing.

There should be more information here; designing what? For example, designing the inside of houses.

I have never went gone to Europe before. I think they are have a different culture than from our those in the East.;)

Tomorrow I plan to draw some pictures of Loki or Tom for myself,ehehehehehehe...

Like when you use "any," when you use "some" make sure you use plural nouns. "Some pictures, some plates, some cities, some people."
