I reviewed the game for you. But please keep in mind, that I'm only about 6k, so what I think is good (or bad) might not be really good or bad.
I also haven't commented someone's game in a while..

(;W[fp]WL[514.402]C[Very bad, inefficient shape (empty triangle) and not really necessary. I guess you were afraid that black would try somethin in the corner? I don't think that black can do something because you have a stone at C3 which can connect either to your stones above or to the right. This limites not only black's possibilities a lot but also the amount of possible liberties the group might get. If you really still do want to connect here, I'd suggest D5.]

;W[jd]WL[503.597]TR[hc]SQ[pj]C[To me, the game looks already quite hard to play as white (if not pretty much over already). Black was able to build a magnificient strength on the left side which readiates around the whole board. White on the other hand has only 4 floating stones on the top and a secure and pretty large territory on the left side and in the lower left corner. Still those stones won't help you from now on to do something agains blacks overall influence. they cannot develop anymore, only squeezed smaller. Black on the other hand has not so much territory but can easily build a moyo which will be extremely hard to invade. Black can also fight to his heart's content because of the strength he built on the left. As your stones on the top are on the fourth line, you'll have a tough time there.
A good idea to play tenuki, but I don't like this move. It doesn't strenghten your two stones to the left because black can still play in between and it doesn't claim territory either (you have played all your stones on the top on the left side and the fourth line is rather for building strength than for securing territory). I'd prefer one of the marked spots instead.
The spot in the upper left corner helps your group in the upper left corner which looks pretty vulnerable to me, the point on the right side looks good to work (a bit) against all the strength and potential that black has in this area. But maybe it's not enough anymore.]

(;W[qn]WL[501.474]SQ[lp]C[Maybe you are right and you should extend all the way down. But it's extremely risky because of blacks strength on the left side. Also, you should play on the fourth line (Q6 or the like) to avoid being pressed low. If black succeeds in pressing you down, he'll get a very large secure territory around the marked spot.]

If you play like in the game you won't get eye space for any of your stones and that's the reason why in situations like this you shouldn't try to save all but some stones. Sometimes it's better to give up some unimportant stones to save others. Although I admit that deciding what's important and what not is not that easy, let alone live in situations like theese.. ^^; Personally, I have no idea how white might be able to live here and I don't think it's possible unless black makes a mistake.]

1. Don't let your groups get closed in.
2. When running with your stones side by side with the stones of your opponent (like on the left side), try to hane as early as possible (taking into account the possibility of your opponent cutting, of course).
3. Learn about / Review the meaning of the fourth line vs. the third line in the opening. ])

).]))
(;W[dl]
;B[em]TR[el][cn][co]C[You now can think about the marked points: Cutting through blacks wall or simply threatening the corner by connecting your D6 stone.
Personally, I like cutting throught blacks wall better because it opens a way for white's group into the center which seems very important to me when I look at how the game continued. You should always take care of your grous in a way that they don't get closed in because if your oponent succeeds in doing so, your stones are practically out of the game. They cannot help you in a fighting situation because you cannot connect your running stones to them and they might even become a burden when your oponent threatens the limited space that remains for them to live (even if it's "only" for ko threats, it might be the ones that let you lose the ko!).]

(;W[dl]C[Disrupting blacks connection here looks good to me, too. Also, D8 is a very nice point concerning the shape of white's group. Black on the other hand has no real base and J11 looks rare and too close to the black wall. It is definitely overconcentrated.
If black defends in the lower left corner now, you still have many options left including approaching the lower right corner, extending along the right side (around the hoshi) or stabilising your upper left corner which is still vulnerable (a move around H17 looks good).]))
