Really nice opening by the way. I much prefer Black after 40 moves.
feels like it should be J5 - that seems to make bD6 wE6 bF5 a pain for White without actually starting a weak group fight. By 74 you feel ripped off somehow.
at E5 feels much more severe somehow.White chose a funny, game-crippling "joseki" in the top left
at H15 feels more severe because of his floating 4 stones lower down?By
, you feel badly outnumbered. Maybe at E12 to fix first?White should play at F12 anywhere between moves 100 and 110
E12 at 114 is still very awkward for Black.
I only took that risk because of the D16 stone. If the upper left were white or empty, I never would have tried it.
is lost, but white's wall is split.
tenuki, 
is left for aji 
is too early. White has nothing devastating here, and there are huge tracts of unexplored edge beyond yonder hills (i.e. in the upper right).
is a huge mistake, r7 is the only move here.
Well, now your c7 problem is fixed 
Should hane, the cut is unreasonable. Perhaps even double hane 
Wrong side, should be K14, attack on a global scale.
Should be K14, the white center stones do not cut anything important and can be efficiently sacrificed with E9 etc. later
at H5? Or did you consider the stones dead anyway and you wanted to prevent white from building thickness?
