I did a score estimate, and I believe that I am still ahead. Black curently has ~22 in the top-left corner, ~8 in the bottom-left corner, and ~12 in the top-right corner. Given all the cutting points in the top-right, Black can expect to make another 10 points there. Top side might give Black additional 5 points. It is hard to estimate how much points Black will make on the bottom or on the right sides. However, if one player takes the bottom, the other player is likely to take the right side, so I'll make the assumption that the net expected gain for either side is 0 from these parts of the board. (I'll revisit this assumption as additional moves on the board are played.)
Hence, Black's score can be estimated as (including the 1 prisoner) B = 42 + 1 + 0-15 = 43-58.
By contrast, White has about 30 points on the left side and about 12 points in the bottom-right corner. However, if White takes a move to reinforce the moyo on the left, White can expect to gain additional 15 points (possibly more, depending on how the situation develops on top of the board). Bottom right corner can likewise be expected to grow by, let's say, an additional 8 points.
Therefore, with the komi, White's score can be estimated as 42 + 6.5 + 0-23 = 48.5-71.5.
To summarize, although the situation is volatile and, thus, conducive to large swings of the score, if I don't cough up too many points as the play develops on top, I should be able to win.
To ensure that the desired outcome of the game is reached, I need to protect my moyo sooner rather than later. In addition to various reductions, such as at "a," Black also has the very annoying invasion at
. Without a reinforcing move (I think "b" works, for example), this invading stone will be able to escape into the center (leaving White with about 30 points of territory on the left--the figure used in the above calculation).

As for the move in the game, I chose to attack the Black stone at L16 with a keima because this move serves to push the Black stone away from my moyo. Moreover, the keima acts to expand the moyo and to reinforce some of the moyo's weaknesses. In response, topazg can choose between the following moves:

One more thing, the White structure in the top-right may look ridiculous with all the cutting points that it contains, but the strcture is not entirely horrible. The point is that it takes time to capture any of these loose stones, and each such capture strengthens the stones that remain. Here is one example:

This series of moves gives Black 10 points, or so, but it also gives White sente and a great deal of influence toward the right side and toward the center. As White, I'd welcome such a capture by Black.
Furthermore, note also that the group Black ended up with in the top right is not efficient at all. The group could have 2 stones fewer without suffering too many adverse effects.
Finally, White made the exchange in sente. Hence, things aren't quite as "rotten in the state of Denmark" as they may seem, as Shakespeare might have said.
P.S. topazg makes his moves very quickly. I found it very hard to resist the urge to move as quickly as he does. However, my game suffers greatly if I don't allow myself adequate amount of time to think over my moves. Thus, I'll try to avoid making this mistake in the future.
I suspect this will get very ugly, very soon. This is my first comment on a Malkovich game, I hope I did it right... fingers poised to delete...
And, yet, I was not sure of the outcome after this move. I'll have to look at it later. Congrats on beating breakfast, by the way.
