I don't think it is, but there is optical illusion on the left side because of the bank not being parallel to the picture - I've already liquified it somewhat, but doing anything more would make it look weird.

I've checked the verticals and they are right. In this case, any "horizon" would not be accurate. Looking at this shot again, I would probably do a reshot closer to the Helix Bridge in future just to emphasize it a little less. Would probably also make the foreground a bit less conspicuous and help with the horizontal perspective distortion here for the MBS bank, IIRC.
No filters used in #84. Of course PP was done. I PP all my shots, it's just a matter of how much.
Thanks for sharing your thoughts! Cheers.
