Some general points:
- Improve your recognition of good shape. You often miss moves which would put you in good shape and or exploit the shape of your opponent's stones. [Solve more Tesuji problems]
- You have the habit of creating many weak groups. This often combines with not playing good shape which has eye-potential or other benefits. If you make a new group it should often have more purpose than just claiming an area. Does it attack something? Does it prevent your opponent from an extension while not putting you in danger to get attacked yourself? See the fourth point. [Solve more Tesuji and Tsumego problems]
- Know, how to defend your groups in need. This mostly means you attach onto your opponent's stones. Sometimes you try to defend but you only give your opponent points and don't get good shape out of it. See the first point. [Solve more Tesuji and Tsumego problems]
- Don't play close to strong positions. Several times, you played close to a strong position from your opponent as if you were afraid, that he might extend and get territory. Don't always fear what your opponent might get but see what you got in exchange for his strong position. [Replay professional games]
- An attack is much more successful when you have strong positions. Don't leave weaknesses behind and then try to attack strongly. [Replay professional games and do more Tesuji and Tsumego problems]
Some more detailed points:
- Don't force your opponent to make a Ponnuki shape! See the first point above. [Replay professional games]
- The Keima shape quite like the large (two-point) jump leave behind cutting points. So don't run away with these shapes, when you have a weak group. [Replay professional games]

A is the only move here (shape). With this move White can just capture at B and make very efficient shape with a large corner. You can look this Joseki up when you want.
You might think that you can also play the Atari at A when White plays B and you extend to C but then you have sacrficed two stones already for an otherwise free Atari.]
;W[ed]WL[1783.11]LB[gc:A]C[SoDesuNe:
Very bad move by White.
This is one of the cases where I think, he just memorized the Joseki and was not sure what to do when you played different from the books.
A is still correct.]
;B[cg]BL[1729.662]LB[eb:D][fb:C][gb:B][gc:F][jc:E][kc:G][ed:A]TR[fc][gd][ge]C[SoDesuNe:
Also bad.
Your marked stones lack shape and will become an easy target. Since White played A, which actually is a pass, you can take the time to defend with no worries.
I would play B I think. C is possible, too, but after White D you need an extension to E, I guess, to cover the cutting point at F.
But E does not work together with your upper right corner stone. A stone on G woud make a nice balance between extension from the corner and from your group because it also works as a pincer when White approaches this corner.]

Don't play near your strong marked group, go all the way to A with this pincer - if you want to pincer.
The thing is, White has always the B to D sequence so your top will not be big. Therefor you can also think about E to G and take the side.]

I must say, I like this move. Black will get overconcentrated even more, showing that pincering and especially with the marked stone, was not the right move.]
;B[le]BL[1596.347]C[SoDesuNe:
You would never like to jump after an attachment, except for situations where you are terrible outnumbered and have to play light. This jump give so many forcing moves to White that his group is already untouchable.
This is great success for White. He has a big corner now and destroyed your side without breaking sweat.]

I would go all the way to A here. The problem with a fourth line extension is always the open skirt, when White plays B and I don't feel that the center becomes important.]

I think you can safely connect at A and when White cuts at B you can play on the second (starting with this move) and capture White.]

This move has a funny relation to your corner stone. It does extend a little but has no extra merit. E.g. if White plays A or B then this extension is not a pincer.
I would either play this at C or D for an extension cum pincer or go all the way to E. Just playing A or B in the first place and take the corner is also good.]
