mmigo: Analyzing need!

[mmigo]

I play weiqi, but not quite a lot.
Here is another match and I have to resign in 140th move. (too bad ha!)
I think I need something important in my middle game.
Please point them out.
What are my weakness? (All parts?)
Which parts to study more and more.

Thanks in advance!

I like it reminds me of the ear reddening move. I dislike B's fuseki. What is his thinking? for example seems to concede half of the board to W. But I am only 7 kyu, who cares!
