That's a very nice overall correction toward what you said you want. You additionally de-crushed the dark areas, which is very nice too! Halfway down in your first image/screengrab set, things get a little orangey with her face, but if you're affecting the entire film at once with de-blueing I don't see how that can be avoided.
As I usually say in my posts, this is all just my amateur two cents as a possible approach; others may chime in with better advice!
That out of the way... If you have a lot of hard drive space, you can use VDub+Lagarith lossless codec to save out a few large chunks of the movie (with different gradings) and then later use the "Append AVI segment" menu option under the File tab with a new instance of VDub to piece-by-piece glue the newly-worked pieces back together (accurate to the frame). You do these appends in chronological order, using that menu option over and over (for each chunk) until everything is in place beginning to end. Then when you're sure it's the way you want you set VDub to "Direct stream copy" (to save time and processing energy), output a new avi that is now it.
It takes a little practice, but I've done this a lot; I like this approach as the upside is it's very solid and robust; you can account for every frame easily. The downside is you end up with a large avi file for the whole (video of the) film, over 200GBs for 1920x1080 (that needs to be compressed to something new afterward of course, ala mp4). But if you have the hard drive space I say give it a try at least once, see if it works for you. (But you should leave the sound out of it with this appending method, more on that ahead.)
You really need to use Lagarith (or some lossless) codec though; saving your corrected chunks out from VDub with a compressy codec greatly diminishes your ability to have solid frame accuracy, and that's putting aside losing general image quality.
To recap, if almost all the scenes in your movie are good with your overall correction except two or three, yeah, you can use VDub to make the few chunks that define what you want, then use VDub's "Append AVI segment" to frame-accurately stack/stitch those, and output to make a new, definitive avi master file of the video. But, yeah, consider this silent work on the video only; deal with the sound separately (muxing later with the compressed mp4 perhaps), do NOT expect VDub to handle your sound nicely when cutting and appending chunks of a movie. (Maybe someone will have better advice on that though; I've always had trouble with that.)
But if you don't want to do any of that with this project — do leave as one overall correction — it looks good, really!
