were excellent moves that can't be faulted. If you are looking for a change in the early opening it would be n5 connect at o2. In the usual joseki continuation white cuts* and black gets a stable group with some points on the lower side, white gets the outside stone to develop the centre/right side and the corner (but not so huge as honte is to fall back to 3-3 in response to the black p2 push, if block black has big aji in the corner). Yeah white's right is big potential, but there's still the r12 gap and you've got big top side potential too.*He might also choose some active pincer instead.
is big. Otherwise, W can peep M3:

tenuki or reduce bottom build strength to invade right.
. Maybe I have to try to play more consciously.
looks quite natural to me. If you get a bad result here later,
did you consider or read the very natural Q7 ? Your opponent jumps in
- 
exchange: you get gote here all by yourself !
W can close you ( in sente? ) with something like o6 ?
yes, jump out. Both sides made mistakes ( 
I also like your variation better.

standard bad habit. Can you see why ?
instead of

on left side. Of course I already played the "standard response" q7 on 
I have read these proverbs about using thickness to attack and to not make territory with thickness. However I did not yet clearly think about it the other way round - i. e. what should I do if the opponent makes territory with his thickness. This may now hopefully change thanks to your review!
Yes I sometimes fall for unimportant small stones/groups. Maybe I'm still influenced by Philidor's proverb "pawns are the soul of chess"... 
tenuki is a mistake. White's 
is a bit slack, as white should have hane'd underneath most likely. Hane at O17 is great, and continuing at O16 is good too. When you take gote in the upper left and white gets to come back here to a situation where black likely should have finished in sente, things look favourable for white.
was on hoshi in the actual game instead 4/3 in the Malkovitch game). On move 
I "deviated" into a kind of symmetry variation, where both sides build huge moyos. I finally lost the game by 9 points due to a stupid blunder worth about 10 points but nevertheless found the initial game position and center fighting quite funny. I'm still completely lost about how to deal with such huge moyos and would appreciate any comment (game shown till move 97). 
feels slow to me. I think black should have kept expanding the moyo to limit white's potential. The cap isn't a huge worry for the time being. 
, but it feels like it puts black a move behind locally. Once white gets that solid connection, it's almost impossible to attack him, while black's stones are cut off.
, white can't stop black from connecting, so keeping sente is best.
is painful. Perhaps the earlier connection should have been at K5 or a trumpet connection?
is big, but it's endgame. Better to protect on the right where white's wall is aiming. If white connects those two stones, black's group can still atari it's way to connection, so there's no real threat.
, maybe attach underneath white's side star point stone?
you should approach white's upper left as in the kobayashi opening, to break up white's moyo potential while leaving black some.
shows quite good perception: up to 
should be K9, but White gets fancy. Black surely should play at J9 before F12. 
atari at N12 and then
